Kuen Surface Model

The beginning of the 20th century saw increasing complexity in the study of mathematics and it heralded the use of three dimensional models as teaching aids. One of these was the Kuen Surface, a rare example of a surface with constant negative curvature, first described by the German mathematician Alfred Enneper (1830-1885).

Item Description: Numbered production. In 1936 Man Ray was hired by the art journal Cahiers d’Art to photograph the mathematical models of non-euclidean geometry at the Institut Henri Poincaré in Paris. These models went on to be exhibited alongside many surrealist and modernist works at the Grand Palais. Man Ray’s series of photographs and paintings called Shakespearean Equations contributed to liberating these forms from the isolation of scientific research, and presented to the public the world of mathematical elegance. This is an accurate representation of the Kuen surface.

Materials: Solid walnut

Dimensions: H: 11" x Ø 5"

Made In: Germany

Our goal is to keep the ordering process as simple as possible. Shipping times vary from 1-3 business days and delivery time varies between 3-10 business days if your product is in stock.

Please read through this instructional guide so you can understand how the process works and what you should expect to happen once you place your order with us.

Order Confirmation:

• As soon as we receive your order, we automatically reach out to our warehouse to confirm that it is in stock and available for immediate shipment.  
• If your item is on backorder or unavailable, we will reach out to you via email.
• If your item(s) are available for immediate shipment, we will process the charges and submit the order for shipment.

• We will send you the tracking information within 24 hours to the email address you provided when checking out.  
• We ship daily via UPS Ground, Fed Ex Ground, and Freight to the lower 48 states. Most all orders will ship the same day as ordered if the order is submitted before 1pm PST (some exceptions apply, some part & freight orders may not ship until the following day).  
• Some parts orders and freight shipments are subject to ship the following business day if the order is placed close to the 1pm cut off time.
• Shipping costs are included with any unit going ground to the lower 48 states. AK & HI ship by AIR at additional cost. 
• We do not offer Cash On Delivery.  
• A phone number is required by the freight company so a delivery appointment can be made.  
• Failure to provide this at the time of order may cause a delay in delivery as freight items will not be delivered without an appointment.   
• A delay in delivery may also cause additional storage fees to accrue that will need paid prior to delivery.

• Customs, Duties, and Taxes: Import duties, taxes, and charges are not included in the item price or shipping cost. The recipient of an international shipment may be subject to customs brokerage fees, import duties, and taxes after the shipment reaches the destination country. Additional charges are the responsibility of the recipient because we have no control over these government-imposed charges and cannot determine what they may be. Customs policies vary greatly among countries. Therefore, we cannot, and will not, offer advice about taxes in your country. We report the amount of the sale on the Customs form. Please do not ask us to claim less than the actual purchase amount. It is the customers responsibility to know the legality of the products ordered in their country. Do not order items that are illegal to import into your country. Laws are different in every country and we cannot keep up with them all. It is your responsibility to check with your Customs office to see if your country permits the shipment of our products to your country.
• As the buyer, it is your responsibility to find out that information before you order. Please contact your local customs office for information.
• To avoid a delay in receiving your order from customs, consider the following:
• Provide us with a phone number where you can be reached by customs when your product arrives. This phone number will be listed on the commercial invoice so customs can reach you to clear your order.
• Please do not refuse a shipment or ignore requests from carriers regarding duty and/or tax liability charges. Be aware that most carriers will hold a shipment for 5 days after arrival in your country before they return it to the sender.
• We do not refund original shipping charges for goods that are refused for delivery at customs.
• We will deduct all additional fees resulting from refused international shipments from your refund.
• If we are charged for YOUR taxes and duties on the shipment or incur any penalty or lawsuit related to your order or shipment, we will post the charge to your credit card.
• If the package is seized by Customs for any reason and we do not receive the package back, we will NOT issue you a refund since, obviously, local laws and regulations determine the fate of the package. If we do receive the package back after being seized, you are still responsible for the shipping charges and any other fees plus penalties incurred.

• We ship via UPS and FedEx for most products, USPS for small parts and accessories, and freight for large products.
• If you don't receive tracking information from us within six business days of your order confirmation, feel free to follow up with us at support@firstclasscaves.com

Cancellations & Refunds:

• All orders canceled are subject to an administration fee equal to 25% of the total order amount, whether or not your order has shipped. This is a fee that covers administrative and personnel fees.
• If your item is on backorder and you accept the backorder, we will hold your payment until the product ships. 
• If your order has shipped, you (the buyer) will be responsible for actual return shipping charges. Refunds will only be issued to the original credit card that you use when placing your order.

CANCELLATIONS

All unshipped orders canceled are subject to a 6% cancellation fee because we incur costs from our credit card processing company after we confirm your product is in stock and capture the payment for your order.

This includes:

• Products on backorder after you (the buyer accepted the backorder)
• Products getting shipped from a different warehouse

If your order has been shipped, the standard return procedure applies.

Refunds will only be issued to the original credit card that you use when placing your order.

PRE-ORDERS

We rely on just-in-time fulfillment from our suppliers to provide you with a vast array of products for sale at low factory-direct pricing. This allows us to cut the costs of overhead and middle-men and pass those savings onto you. Sometimes, products are so popular that they go out of stock before the next shipment arrives at our suppliers warehouse. 

If the product you purchased is out of stock at the time you placed your order, we will notify you via email as soon as possible and give you the ETA as well as other options that are currently available.

If you can't or don't want to wait, you can choose an alternative product. At that point we will either charge or refund you the difference, update your order, and ship out the alternative product.

If you don't want an alternative product, you can cancel your order without any cancellation fee.

If you choose to accept the ETA and wait for your product, you order will be placed on pre-order status. This means we will place the pre-order with our supplier so that the product is reserved upon arrival and will ship out to you as soon as it arrives.

If you choose to cancel your order after you have confirmed your pre-order, and it still hasn't shipped yet (like in the case that it gets delayed further) then you will be charged the 5% cancellation fee we must charge to recoup the losses we incur from our credit card processing company when we issue refunds.

If you choose to cancel your pre-order after the product has shipped, the normal return policy applies.

Thanks for your understanding.
