Melissa & Doug Sticker WOW! is a whole new way to play with stickers! Pop the convenient sticker stack of 200 assorted favorite things stickers into any Sticker WOW! Sticker Stamper cartridge (sticker stamper not included), and stamp, stamp, stamp through 24 mini pages (approximately 2.25 by 4.25 inches) of fun-filled favorite things-themed counting and matching activities. With 100 unique designs in the sticker stack, each sticker stamped is a surprise. Sticker WOW! refill stickers are not reusable but are easy to remove if necessary and are great for creative arts and crafts projects. Favorite Things refill stickers are a natural complement to the Unicorn and Ice Cream Sticker WOW! sticker stampers, but they are compatible with all the cute and collectible Sticker WOW! sticker stampers.
