Hey everyone who's dealing with falling shower caddies! These LAIGOO replacement adhesive hooks are absolute lifesavers for keeping your bathroom organizers securely mounted! The pack comes with 8 pieces in two different sizes - some are 5.5x2.36 inches and others are 2.36x2.36 inches, giving you flexibility for different mounting needs! Now, here's the crucial part - these adhesives ONLY work on smooth surfaces like ceramic tile, glass, smooth wood, metal, or flat marbles! Do NOT stick them on painted walls or wallpaper because they will absolutely take off the paint or paper when removed! The installation is straightforward but important to get right - make sure your surface is completely dry, smooth, clean, and free of major bumps before applying! When sticking them on, you need to really press firmly and squeeze out all the air bubbles to ensure maximum adhesion! These are specifically designed to work with adhesive bathroom shelves like models B07SJ2QZGV and B07V2L4PP8, but they'll work with most similar products! The transparent color is great because it blends in with most tile and doesn't stand out visually! What's really helpful is having replacement adhesives on hand for when your original ones start losing their grip! They're perfect for renters or anyone who doesn't want to drill holes in their bathroom walls! Just remember they're not suitable for uneven surfaces, limed walls, rough marble, or concrete walls! Having these backups means you can quickly remount your shower caddy without having to replace the entire unit! For the price, you're getting reliable mounting solution that keeps your bathroom organized and your products within easy reach!
