Do not use for anything other than its intended purpose.
This product is designed to be hooked on the top of the shower hook and to prevent it from slipping with a suction cup. It cannot be used only with a suction cup.
Check the load capacity of the shower hook and whether it is firmly attached to the wall surface.
Please use within the range of load capacity. (Estimated weight: Approximately 750 g when shampoo etc. is added for pump type bottle 600 ml)
It may be difficult to attach a suction cup that has come off or has become old. Put boiling water in a bowl, soak only the suction cup for 5 to 6 minutes, and dry it before use.
