These are transparent adhesive hooks! They have strong adhesive power, so unlike suction cup types, they won't easily fall off over time, and unlike magnetic types, the installation surface won't shift. For example, it's disappointing when a sponge you hung on a hook in the bathroom falls off, but with this product, you can use it without stress. Also, the weight capacity is a whopping 20kg. We recommend using it within a reasonable range, as it may vary depending on the usage situation and installation environment. As for uses, you can of course use them as key hooks, but you can also use them in various ways, such as hanging them in the kitchen or using two to store a frying pan lid. In addition, they can also be used in workplaces and kitchens! Places where they can be installed include flat surfaces and walls, stainless steel, tiles, painted metal surfaces, and plastic. ~Product Details~ Material: PVC + Metal Size: 6 x 6 cm Color: Transparent Usable Locations: Kitchen, bathroom, refrigerator, walls, etc. ~How to Use~ ① Wipe the surface to be installed clean. ② Peel off the transparent sheet. ③ Stick the adhesive part to the wall, making sure there are no air bubbles.
