This shower caddy has clever storage for your shower essentials including body wash, shampoo and conditioner, razors and loofas. 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. Use All Your Shampoo. 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. Flex Gel-Lock Bin measures 3 x 13 x 4 inches (9 x 33 x 11 cm). For best results, we recommend tightening the GEL- LOCK knob once a month.
