Everloc is a real revolution in the realms of suction-fix products. A DIY (do-it-yourself) dream. When the suction cup is applied, a silicon ring first adheres to the surface and creates an airtight seal around the suction cup. This patented Everloc system is probably the only suction cup system that delivers what it promises: Long-lasting adhesion and consistent load-bearing capacity. Easy to assemble. NO tools, drills or glue. Comes with everything you need. Dorm proof suction! No need to worry about damaging your walls and best of all this is suction that actually works. This Bottle Basket really comes in handy when you are sharing a shower with your roommate and suitemates. The reason it REALLY comes in handy is that most showers severely lack shelf space to keep your bottles up. With 4 or more sharing the shower you can do the math that somebody's shampoo bottles are on the outs. With our Bottle Basket you can now keep your shampoo, conditioner and other bottles in the shower, instead have having to bring them in and out with a shower tote. This basket brings convenience and ease, while having the strength to hold all your over-sized bottles. Suction to your shower tile!
