Traditional agitating devices such as the coil, grate and screen have had no problem standing up to the harsh effects of mineral solvents over time. Onn the other hand, your favorite brushes have always had even more trouble standing up to unforgiving abuse from these devices!
Finally, a new solution. The Mini Puck starts out barely larger than a quarter. Soak it in your turpentine for as long as you'd like, and it will literally GROW for hours until stopping at the perfect size, fitting snugly at the bottom of your favorite small jar or metal canister.
The soft, gentle nubs preserve your brushes far better than any rigid alternate, and when its time to empty out the turp, the Puck will shrink back to its starting size! Your brushes still get the most gentle, compassionate treatment! A perfectly balanced chemical reaction!
