From our humble beginnings in a garage in Valley Center, California in 1981, this family-owned and operated business has grown to become the largest of its kind in the world. With a state-of-the art manufacturing plant and a highly trained staff, Therm-O-Boss® Corporation is the world's leading manufacturer of the finest powders for the thermographic (raised letter printing), artistic, and rubber stamp applications. 

These include crystal clear, metallic, pearlescent and laser-safe powders, which are used on letterhead, business cards, social announcements, certificates and greeting cards. Whenever you feel raised lettering on those items, there's a good chance that the powder that created that effect is Therm-O-Boss powder. In fact, our exclusive products have been used to add beauty and excitement to printed materials for nearly thirty years.

As a manufacturer, we sell strictly at wholesale to both distributors and commercial thermographers in over 50 countries around the world. 

Virtually every colored powder with or without glitter you see in rubber stamp stores, arts and crafts stores, and catalogs originally came from this company! ALL of our products are certified non-toxic, and comply with ASTM-4236D and the CE label in Europe.

Enjoy browsing our website for ideas and what you may be interested in ordering. There's a lot more here than what you see in most stores and catalogs, so if your retailer or distributor doesn't have what you want, just ask them, and they can get it for you. 

We're dedicated to Research and Development, continuously developing new and innovative products and methods for rubber stampers, artists and thermographers.
