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