KORCCI Suction Hooks 12 Pack – Heavy Duty Clear Suction Cup Hooks, Reusable & Removable, 4.5KG Strong Hold with Stainless Steel Hook, for Bathroom, Shower, Window, Kitchen, Tile

Absolutely brilliant, they are very strong, they stay up very well on glass and the hook is optional. They hold up Christmas card strings a treat!

Great hooks - currently holding up my Christmas lights and a large garland down the glass sided stairs - no problems - they haven’t fallen off!

Excellent suction cup hooks I bought them to hold Halloween decorations up in the windows. Very strong suction seal, can hold a good weight on glass. Should be good for a good range of uses-especially holding things in showers or on windows and cupboards.

These stick well to glass but no so well to UPVC (though it wasn't so clean so will try that also). Easily removable which is what I wanted and can restick these. Can be used for multiple things too. Arrived quickly and seem study, all hooks present etc, so good buy. Expect some plastic suckers and small hooks to cost less these days but overall should do the job to hang a projector screen.

Thought would stick anywhere but only to windows, had to us screw in's in the end do not much use to me really. Good suction on windoes though

These are fantastic, hold a good amount of weight, stay stuck but easily removed. Happy customer.

Brilliant hooks for putting up Christmas decorations. They can be used all year long ,I'm sure i will find lots of uses for them

Does not adhere to wood, this is what i bought them for......
