Can be used under a glass table or a children's plate. Ideal for holding cell phones, aquarium decorations, string lights, and craft projects. Suitable for replacing worn suction cups. Soft silicone rubber resists crushing and wear. If the suction cups become deformed, soak them in warm water for approximately 2 minutes to restore their shape. Suitable as shock absorbers for transporting flat glass and mirrors. Provides secure hold to separate and cushion parallel surfaces in a horizontal position. Adheres to a wide range of smooth surfaces including ceramic, stainless steel, glass, mirror, refrigerator, and metallic paint. Also suitable for other smooth, non-porous surfaces. Machine washable. For best results, ensure the surface is clean, dry, and free of debris. If air enters between the cup and the surface due to irregularities or contamination, adhesion may weaken. Clean the suction cup if dirty, then soak in warm water for about 1 minute to restore original shape before reuse.
