I came upon this when I was looking at something else the other day. It is for developing clear stamps but you could check out the information at least. The direct website is:
http://www.stewartsuperior.com/html/...ring_serv.html and it is way at the bottom of the page.
Interested in developing a clear stamp product line?
Give us a call - don�t go to market with anything less than Superior ClearTM.
Our manufacturing service for Superior ClearTM stamps is affordable and easy. All manufacturing duties are handled by our expert staff and you receive finished product ready for packaging. Plus, with clear stamps there is no trimming, no cushion and no mounting labor or wood mount costs. And the shipping costs less too!
