I can't say I've ever seen collapsable pails! Going to the beach, we haul SO many things! And even if we go for just a couple of hours, it's still a pretty big haul. But now we don't have to bring the big bag of sand toys! These fold FLAT and can just fit in the backpack! My girls also use them for activities around home or the lake. It's like we have "instant pails"! Need a pail? Just pull it open! Easy to pack away and have at our convenience! We've taken them on a hike before - my youngest likes to find rocks, mushrooms, interesting leaves - and the pail is the perfect size! Getting three pails in this set is a great value!
