MUJI PCM Neck Cooler

🟢 Product Description

This neck cooler naturally solidifies at approximately 28°C, providing a comfortable cooling effect around the neck.

It can be reused repeatedly. When it becomes soft in warm environments, placing it in a cool indoor space (such as an office or café with air conditioning) will help it harden again.

Because it solidifies at 28°C, it can be re-cooled easily without electricity or water freezing.

🟢 How to Use

1. Place the product flat in a refrigerator for about 20 minutes, or in a freezer for at least 5 minutes until the inside hardens.
2. It can also harden in water below 28°C; lower temperatures make it solidify faster.
3. Wear it around the neck after it becomes solid inside.
4. It is reusable.
