In the indoor playground, the playland castle is definitely a wonderland that children can't resist. The ocean ball pool here is a feast for colors and textures – there are not only common solid-colored balls and rainbow gradient balls, but also printed balls with cartoon patterns, slightly luminous glow-in-the-dark balls, and even custom-made commemorative balls printed with family-specific logos. This variety allows children to release their energy freely in the sea of balls. More importantly, every ocean ball undergoes strict safety testing, with smooth, burr-free edges. Made of food-grade PE material, they are non-toxic, odorless, and anti-extrusion, so parents can rest easy even if their children bite them.
