【Long-Lasting Reusable Cooling for Fever & Hot Nights】Hakugen Aicenon Cooling Pillow | Made in Japan
■ Product Features
Hakugen Aicenon is Japan's classic reusable cooling gel pillow, trusted by families for decades for managing fever, hot summer nights, and post-exercise heat. Unlike disposable cooling sheets, Aicenon can be chilled in the refrigerator or freezer and reused hundreds of times — making it both economical and environmentally friendly.
The inner gel maintains a consistently cool temperature for an extended period after chilling. Simply place it under your head, on your forehead, or against any area needing cooling relief. The soft, washable outer cover ensures comfortable skin contact and prevents condensation from reaching bedding or furniture.
Measuring approximately 12cm × 17cm, Aicenon is sized ideally for forehead use, neck cooling, or as a compact pillow insert during sleep. Its flexible gel construction conforms gently to the body's contours, ensuring maximum surface contact and cooling efficiency.
Completely drug-free and chemical-free, Aicenon is safe for the entire family including young children. A true Japanese household staple that provides reliable cooling relief season after season without ongoing cost.
■ Recommended For
· Those managing fever and seeking drug-free temperature reduction
· Families wanting a reusable, eco-friendly alternative to disposable cooling sheets
· Athletes and active individuals needing post-exercise heat relief
· Those who sleep hot and want a natural, refreshing sleep aid
· Anyone needing versatile, portable cooling for home, office, or travel
