Washable stamp pads offer a variety of creative possibilities with easy cleaning! The ink washes off fingers and most clothing with warm, soapy water. The quick-drying, fade-resistant ink is also acid-free for archival quality. The pink, purple, turquoise and green ink in this stamp pad presents crisp, vivid images when stamped. Stamping is a fun way to develop fine motor skills and foster creative expression. The ink pads are packaged in a plastic case with a flip cover to prevent them from drying out.
