TONIC WATERCOLOR HALF PANS Our original watercolors are now available in traditional half pans! This is the classic little 'chiclet' shape that you'll find in most modern watercolor sets. Ours are taller than most, and they're generally overfilled. We actually fill each one of these by hand, if you can believe it, so there are minor differences between each pan. Tonic half pans fit into any standard watercolor tin. Made right here in St. Louis, MO. ABOUT TONIC WATERCOLOR Tonic Watercolor is made right here in our St. Louis HQ, with a unique formula that we developed over two years of experimentation and research. We designed Tonic for maximum pigmentation, and you'll notice that a pan of Tonic is more concentrated than many other artist-grade watercolors.
