I'm selling this because I bought it but no longer use it. I've only used it a few times, and it's in very good condition. It cost 2880 yen when I bought it. [Size adjustable from S to XL] You can use it for a long time, adapting to your child's growth until they are potty trained, thanks to the snap button adjustments. [Prevents leaks] Made with waterproof and quick-drying polyester material, and features back and crotch gathers to prevent side leaks, ensuring peace of mind until morning.
