YuunySleep ・ YuunySleep Pillow ・ Cooling Touch Cover Purchased in June. Used only once in July, but the child slept in a high-low chair, so it has been stored in the closet since then. Although it has only been used once, please understand that it is a used item, so there may be some signs of use. There has been no spitting up, etc., but there is a small yellow stain on the cover. (A few centimeters in the middle right of the second photo) It may come out with scrubbing or bleach, but since it is for a baby, each household has its own washing method, so I have not removed it. Home cleaned with baby detergent. Please understand that this is a used item before purchasing.
