The Mixing Cup is the perfect vessel for modifying head cements and UV Clear Fly Finish, and all but eliminates clean-up. Because cements will not bond to the Mixing Cup, once cured they will pop out.
Suction the Mixing Cup to your work surface. Mix your perfect combination of cements, thinner, and/or fly tying powders. Cure cement and pop out.
I have begun using with powder and epoxy from Loon to coat spoons. It looks great and is easy to clean after usage.
