goKelvin Suction Cup for Signs 1-3/4 inch (45 mm) - 10 Pack - Made in USA (Medium)

These suction cups are fantastic — they stick firmly not only to glass but also to metal surfaces. I’ve been using them at work to hang Christmas lights and birthday decorations, and they’ve made the process so much easier. Before, we relied on Scotch tape, which was frustrating to remove afterward. With these, it’s simple: stick them where you want, run the decorations through, and when you’re done, just pull them off cleanly. Durable, reliable, and a huge upgrade for hassle‑free decorating.

I'm using these for hanging lights on my windows and these worked great. I put the cord through the slot and these hold great for my use.

These holders were good on the inside of the windows on my classic cars holds the signs that say do not touch

Works very well. It will even hold a single sheet of paper securely. Easy to remove paper by sliding it sideways.

I hang signs in our store windows, not heavy, but heavier than normal paper. I've always had trouble getting suction cups to stick or stay stuck to the glass, and didn't like using hooks or punching holes in the signs. This clip solved all of those problems. They work great - so glad I gave it a chance.

Held up Christmas decorations well

I used these to keep a sunvisor on my back windshield. The suction cups that came with the sun visor were useless. These work fantastic!

The suction cup itself seems to hold OK, but the overall product is a failure. There are 2 big problems. (1) The suction cup is not attached to the clip at all, it just slides in--very loosely. So, if you want to use the clip sideways (I want a clip on 4 sides), the clip slides off the suction cup. (2) The clip won't hold my materials. I've tried thinner and thicker, and the clip just slides off--there's no grip at all. Maybe if your material is super thick, so that the clip is "maxed out," it would hold. I cannot use these at all. The only good thing is they are all plastic, so there's no metal to rust.
