Face-down sleeping prevention belt only I've been using Snoo and have purchased this many times for replacements. This one was purchased towards the end, used once or twice, and stored at home. I think it's in very clean condition. Perfect for size changes from S size or for replacements. Also, I have the following, so if anyone wants them for replacements, etc., I'll include them as a bonus, so please comment. ① Large size belt only (with pilling and signs of use) ② Small size belt only (with pilling and signs of use) ※ Box and instructions are not included. ※ Please check the condition in the images. ※ Please note that this is a personal inspection and home storage. ※ This is a used item that a child has used, so please understand. This is a belt to prevent your child from sleeping face down. Thank you for looking.
