The collapsible buckets are a game changer for beach trips. They save space and are lightweight, fitting easily into backpacks for beach trips, camping, or travel. When expanded, each bucket holds up to 2.5 liters of sand, water, or toys. When it's time to pack up, simply collapse the buckets flat. They take up almost no space in your beach bag, leaving room for towels, sunscreen, and snacks. This space saving design makes the set perfect for families with limited storage or for those who love to travel light.Warning:Adult assembly required. Keep assembly parts away from children during installation.
