Ingenious and very practical. This blue mat (19.5cm x 8cm) is covered in small suction cups on both sides. Position it on any flat, non-porous, clean surface in your shower cubicle. You then simply push your bottle of Shower Gel or Shampoo (or both) on to the outside surface of the Squid and the tiny suction cups will hold your bottles in place all day long. No longer a need for unsightly wire racks or bottles stood on the shower floor.
