The Strongest Suction Cup Hooks:Tired of tile hooks that let you down? Our strong suction cup hook is inspired by the vacuum principle of an octopus, featuring a multi-layer nano-scale polymer structure for weather resistance. With a maximum load-bearing capacity of 5KG, it prevents hardening due to temperature changes, ensuring your items stay put without the worry of falling. Second Generation Suction Cup Hook:Our hooks come with a more humanized design, offering a simple hook and a slim double hook. Easily switch between the two types to suit your needs. The slim hook is perfect as a suction cup towel rack, bathroom hook, or bathrobe hook, while the single hook is ideal for clothes, backpacks, hats, and more. Installation is as easy as 1 second! No Sticky Residue, Marks, or Damage:Say goodbye to drilling with our no-drill suction cup hook. Simply remove the protective cover and press onto a smooth, unplastered, flat, and non-rough surface until you hear a "PUFF" sound. The suction cup will be securely attached (and can be removed with a hard, thin card). Ideal for renters, this hook leaves no trace behind. Removable Suction Cup:Our eco-friendly, non-toxic, odorless suction cup hook is made of waterproof white plastic, perfect for long-term use in humid environments like bathrooms or showers. Worry not about bacterial growth. To reposition, just remove the suction cup and rinse it. Please note that it is not suitable for plastered walls, cement walls, mosaic surfaces, or slightly textured pottery. The strong suction cup securely holds towels, coats, keys, hats, handbags, doorplates, and crowns on tiles, refrigerators, or windows in various rooms.
