Most stroller clips don't work. They slip, snap, or pinch — and you're back to picking things up off the ground two minutes later. whimSi clips® are different. Built with a patent-pending silicone spring and zero metal parts, they grip blankets, toys, and essentials securely to strollers, wagons, and diaper bags — without pinching, rusting, or losing their hold. Made with food-grade silicone. BPA-free, BPS-free, and dishwasher-safe. Free shipping on 2+ sets.
