This large stamp pad contains red, yellow, blue and green ink pads within one case. Washable stamp pads offer a variety of creative possibilities with easy cleanup! 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 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 red, yellow, blue 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 flip cover to prevent them drying out. For ages 3+. Size of each color: 3.2"L x 2"W. Size of entire stamp pad (with plastic casing): 6.7"L x 4.9"W x 0.75"H.
