This is a case for neck rings that are used chilled. It contains a cold pack, so please chill it in the freezer before use. It will revive neck rings that have become lukewarm. It's convenient for outdoor activities and casual outings. It has a carabiner, so it's easy to hang on your luggage, and it's convenient to attach a strap for easy carrying. The simple beige color can be used by both men and women. I have used it about twice.
