WaterElf was born from a simple but powerful idea: to capture the calming, refreshing essence of water and transform it into everyday joy. Our story begins in the early 1990s, when our founder’s family started experimenting with creative play materials in Hangzhou, China. What began as small batches of handmade putty and slime quickly grew into one of the world’s leading OEM/ODM factories for global toy brands. For decades, our factory crafted products for international names sold across North America, Europe, and Asia—quietly becoming the creative engine behind millions of children’s smiles.
But WaterElf is more than just another toy brand. It represents a new chapter: a leap from factory floors to global shelves under our own name. Inspired by the purity and energy of water, WaterElf creates slimes, putties, and sensory play companions that combine fun, relaxation, and imagination. Each collection—from crystal-clear putty to glow-in-the-dark slime—is designed to spark creativity and offer stress relief for all ages. At its heart, WaterElf carries a mission of play with purpose. A portion of our profits is dedicated to supporting children’s hospitals, so every squish, stretch, and sparkle helps bring hope and healing to those in need. Today, WaterElf stands at the intersection of play, design, and well-being, evolving into a lifestyle IP brand with collectible characters, themed worlds, and immersive experiences. Just like water itself, WaterElf adapts, flows, and brings life wherever it goes—spreading joy one slime at a time.
