■ Product Features
NASA-developed PCM Material: Naturally freezes at temperatures below 28°C (82.4°F). Freezes even faster if placed in a freezer or cold water.

No Condensation: Unlike ice, the surface does not get wet, so you can use it comfortably without wetting your clothes or neck.

Reusable: No batteries or charging required, so it can be used repeatedly, making it eco-friendly and economical.

Moderate Coolness: Not too cold, so there's no risk of frostbite, making it recommended for children and those with sensitive skin.
