Wholesale Catalog

Wholesale Catalog

We are pleased to offer wholesale pricing to museum gift shops, bookstores, educational retailers, and others engaged in selling quality tools for learning to the public. Our wholesale discounts are 30%-50% off MSRP depending on order quantities. We offer Net 30 terms to accounts in good standing. Wholesale orders are charged shipping at cost, or we can use your shipping account. Payment by Paypal, Credit Card, Bank Transfer or Check. International orders welcome.

All kits are attractively packaged in clear retail boxes with full-color inserts and UPC codes. Boxes are designed to shelve either wide or edge on, like books. These kits are designed and manufactured at our studios in Champaign-Urbana, Illinois. They are made of high-grade clear and colored acrylic, and include all tools needed for assembly (screwdriver and/or two wrenches). Detailed step-by-step assembly videos for each model ensure customer satisfaction, and we provide replacement parts directly through our website.

See below for prices. Please direct wholesale enquiries to theodore@theodoregray.com.


Point-of-Sale Display

For bricks-and-mortar retailers we have available a delightful, interactive point-of-sale display that lets visitors interact with two of the models. The display is made of robust, kid-proof acrylic with industrial-grade push buttons. When either button is pressed, the corresponding model comes to life (powered by a small electric motor in the back), and a set of LED lights illuminates the "billboard" mounted in the center of the display, and the two models. The display is battery-operated so it can be placed anywhere. Four D batteries (supplied) will power the display for a very long time.

Watch the two videos below to see the display in operation.
