TONIC WATERCOLOR HALF PANS, PRIMARY TRIO 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. Our Primary Trio includes three great mixing colors: #325 Quinacridone Magenta, #047 Permanent Yellow, and #245 Ultramarine. 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.
