As a product designer, occasionally I make something even if the invention doesn't fit our product category (farm and garden). Then it goes up for sale or license. Here is an example of such a product that is FOR SALE.

SpecMate™  eyewear caddy

Rubbery, yo-yo-sized caddy holds Rx and sunglasses securely to a window or mirror. Prevents your expensive glasses from getting scuffed as they slide across the dashboard. No more sitting on your frames. Keeps sunglasses one-hand accessible in a vehicle.

U.S. Patent No. 6,530,661

For sale or license: rights to manufacture and sell in the U.S., 2-cavity tooling.

Call (360.331.5242, ask for Dan) if you have questions and/or would like a sample. SpecMate is a simple product that really works great!
