TISKEN series puts things within easy reach without having to drill any holes into your walls. The tight-grip suction cups won’t let go of smooth surfaces like glass or tiles – unless you want them to. Water drains easily through the holes in the bottom. One push assembly - clean the wall surface and push to attach. No tools are needed. To release and remove, insert a credit card (or similar) between the suction cup and the wall. No ugly holes or marks are left behind. The suction cups have a tight grip on smooth surfaces like glass or tiles.
