This large black stamp pad contains washable, non-toxic ink. Washable stamp pads offer a variety of creative possibilities with easy cleanup! The ink is safe for hand and finger stamping and washes off skin and most clothing with warm, soapy water. The quick-drying, fade-resistant ink is also acid-free for archival quality. 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. The black 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 pad is packaged in a plastic case with a flip cover to prevent it from drying out. For ages 3+. Size of ink pad: 6.2"L x 4.1"W. Size of entire stamp pad (with plastic casing): 6.7"L x 4.9"W x 0.75"H.
