Dive into mess-free fun! The pool party theme makes it a great summer activity…or break it out when the weather outside is frigid and you’re dreaming of warmer days. Either way, kids can use the included to reveal hidden images, play pool party bingo and so much more. Hand these out as birthday party favors, pool party activities (for when kids need a break from all the water fun) and everyday creative play. Safe and non-toxic. 8". Includes 3 sets.
