I purchased this at the YAMAP Store, but I never had a chance to use it and have been storing it. As you can see in the second photo, there is some slight discoloration in the center of the storage bag. Please understand that this is a used item before purchasing. ◾️Product Description The COCOON Travel Sheet made of cotton is a comfortable travel sheet with insect repellent function. - Brand: COCOON - Model Name: Travel Sheet - Material: 100% Cotton - Features: With insect shield function
