The patented gel-lock technology allows you to lock the suction cups into place, activating a vacuum seal for an extreme hold that lasts. For best results, mount Flex Gel-Lock on flat surfaces such as glass or smooth titles. Designed to organize shower essentials, this corner shower bin has an integrated soap dish and space for shampoo, conditioner, body wash, a razor, plus two hooks for loofahs, washcloths and more; the flexible band in the front allows for increased storage.
