The stickers are professionally printed on a gloss vinyl which means that they are waterproof and your play mat can still be wiped with a cloth and rolled up when playtime is over.
This In Transit - USA sticker sheet includes all 20 stickers as shown in the first image. Each sticker measures 3/4 inch.
