Purchased at a souvenir shop in Hokkaido. I opened it once to check the contents, but it has not been tried on and is unused. The virgin tape on the bottom is still intact. An Ikura (salmon roe) eye mask for both cooling and warming, providing a comfortable feel with 600g. It looks just like real ikura. - Product Name: Ikura Eye Mask - Usage: For both cooling and warming - Contents: 600g - Weight: 100g - Storage Temperature: Store below 5°C - Features: Hot & Ice
