Have you tried “Cooling gel sheet” called “Netsisama sheet”?

The most popular cooling gel sheet called “Netsusama sheet” was developed in 1994 by Kobayashi Pharmaceutical Co., Ltd. It brought a new method to cool down your body temperature. It’s very simple and easy to use the sheet. You just put the sheet on your forehead. That’s it!
The sheet contains sufficient moisture and it evaporates when the heat is absorbed, so the sheet keeps
chilling the temperature of your skin for approximately for 8 hours.

You can use the sheet when you have a fever and cool down your body in the summer and so on.
This Netsusama sheet has more than 50% share of the domestic market.
In 1996, the company decided to expand the market overseas, starting from Hong Kong, then South-eastern Asia. The company studied the real needs of each country and proposed the usage and products to meet the customer needs.
