Keep gels, oils, lotions and creams just above body temperature with the Warmer. To ensure consistent heating, each bottle sits in its own sleeve and is kept warm by an industrial heating element that uses a minimal amount of power. All bottle warmers are constructed of stainless steel and come with a front mounted, illuminated on/off switch, 6' grounded hospital grade power cord, thermal fuse to prevent overheating, table/wall mounting hardware, and bottles.
