The Melissa Doug Reusable Sticker Pad Prehistoric drops kids into the age of dinosaurs with five glossy background scenes covering the prehistoric ocean, Triassic, Jurassic, Cretaceous, and Ice Age eras. More than 185 cling-style stickers stick easily, peel cleanly, and reposition again and again. Kids can rebuild the same Jurassic scene a different way every time. From Melissa Doug. Recommended for ages 3+ Years 5 background scenes spanning prehistoric ocean through Ice Age Includes 185+ reusable cling-style stickers Reusable cling stickers solve the one-and-done problem with most sticker books. Kids who finish a scene can pull everything off and start again, which makes the pad pay for itself across rainy-day afternoons, long flights, and grandparent visits. Dinosaur-obsessed kids get five different time periods to play across, so a single afternoon can run from the bottom of the prehistoric ocean to the woolly mammoths of the Ice Age. The pad also stores cleanly in a backpack or activity bin between uses, and the cling stickers stay put on the page rather than getting lost between sessions. Older siblings can use the same pad to quiz younger ones on which dinosaurs lived in which era. The five-scene format also makes the pad a credible quiet activity for restaurant booths, hospital waits, or any time a kid needs to sit still for a stretch.
