The Umbra Flex Gel-Lock Bin has clever storage for your shower essentials including body wash, shampoo and conditioner, razors and loofas. The Umbra Flex single shelf bin features Gel-Lock Technology. Our patented Gel Lock Technology allows you to lock the caddy’s suction cups into place, activating a vacuum seal for an extreme hold that lasts. The Flex Gel-Lock Bin allows shampoo and soap bottles to be stored flipped over so you can maximize how much of the product you are able to use. The drainage holds (also integrated) help keep the caddy neat. This shower bin is rust-proof and removable, made from durable plastics that have been tested for strength and longevity. Umbra Flex Gel-Lock Bin measures 3 ½ x 13 x 4 ½ inches (9 x 33 x 11 cm). ⓘ For best results, we recommend tightening the GEL- LOCK knob once a month.
