The Kobayashi Netsusama Sheet is a cooling gel patch designed for adults and children experiencing fever, headaches, or heat discomfort. This value pack contains 64 sheets divided into 4 boxes of 16 sheets each, providing convenient relief for the whole family. Each sheet features a cooling gel formula with menthol beads that delivers up to 8 hours of continuous cooling sensation by absorbing heat from the skin surface. The adhesive design ensures the patch stays firmly attached to the forehead even during sleep and movement. Made with a gentle, weakly acidic formula, these sheets are safe for sensitive skin and free from artificial fragrances. The adult version is larger than children's versions and contains more menthol for enhanced cooling effect. Best suited for sudden fevers, toothaches, post-exercise cooling, or hot summer nights when you need quick, soothing relief without medication.
