This dye ink is excellent for stamping, stenciling, and direct-to-paper applications. The unique shape of the fabric-topped pad offers more options-- use the narrow tip for corners and details and the round end for covering large areas. The container is free standing and the wrap-around label makes color recognition easy. The ink itself is water-based, fade resistant, and acid free.Details:Greenhouse color set1.875" x 1.25" x 0.875" ink pad size4 ink padsConforms to ASTM D4236Water-based dye inkArchival and acid freeImported
