Abstract

Selon cette invention, le polissoir pour les pieds comprend une âme expansée en polyuréthane qui est recouverte de matériau abrasif particulaire. Le polissoir résiste à l'eau, est entièrement lavable et peut être utilisé mouillé ou sec. Ce polissoir est utilisé pour éliminer l'accumulation de peau sèche et rugueuse, en particulier sur les pieds et les mains. La texture douce et souple du polissoir garantit un confort et une facilité d'utilisation lors du polissage de l'épiderme. Les grandes surfaces intérieures incurvées servent à polir les talons tandis que les côtés arrondis peuvent être utilisés pour de plus petites zones, telles que les orteils.
