Hamee Corporation is launching a new Chiikawa-themed smartphone cooling sheet on June 2, 2026. This innovative product, called “Suma-Hie Premium,” is designed to help manage smartphone temperatures and prevent battery degradation, making it an essential accessory for the summer months.
Visitors and residents in Japan can look forward to this limited-edition design, which features popular Chiikawa characters. The cooling sheet is not only functional but also visually appealing, making it a perfect addition to any smartphone, especially when displayed in a transparent case.
About the Product
The “Suma-Hie Premium” cooling sheet is designed to absorb heat from the smartphone, preventing common issues such as battery degradation, reduced charging speeds, and unexpected freezes. The product uses microcapsule technology to absorb heat, which is then released into the air, allowing the sheet to be reused indefinitely.
The sheet is easy to apply and remove, thanks to its silicone gel adhesive, and is only 0.9mm thick, ensuring compatibility with most smartphone cases. It is ideal for watching videos, gaming, or using navigation apps while driving. Moreover, it supports Qi wireless charging, although compatibility may vary based on device and case combinations.
