This red stamp pad contains washable, non-toxic, quick-drying ink. The ink is fade-resistant and acid-free for archival quality. The ink in this stamp pad presents crisp, vivid images when stamped. The raised pad means there are no hard edges around the ink. Children can press down without hitting an edge, which provides more area for stamping. Washable stamp pads offer a variety of creative possibilities with easy clean-up! The ink washes off skin and most clothing with warm, soapy water. Stamping is a fun way to develop fine motor skills and foster creative expression. The ink pad is packaged in a plastic case with a flip cover to prevent it from drying out. For ages 3+. Size of entire stamp pad (with plastic casing): 3.9"L x 2.75"W x 0.6"H; Size of ink pad: 3.4"L x 2"W.
