Pinata Colors are highly-saturated fast-drying alcohol inks for any surface including glass metal plastic ceramic stone leather epoxy resin polymer clay YUPO and more. Indelible and impervious to water Pinata Colors clean up with alcohol and re-wet themselves allowing for unique effects and techniques not easily achieved with water-based inks. Only the most lightfast dyes have been selected for the palette and special formulary technology allows more color into each bottle. Possibly most impressive is the Pinata Colors opens up for non-porous surfaces. By easily re-wetting with alcohol blowing the color across the surface with air moving the surface by hand pouring or applying with a paint brush you can achieve incredible effects. Acid-free and with excellent adhesive properties Pinata colors are the go-to inks. Conforms to ASTM D4236. Made in the USA.
