Kepfire 20Pcs Double Sided Suction Cup Reusable Rubber Clamps Aquarium Oxygen Hose Pump Clip Fish Tank Transparent Sucker Pads Accessories

I think other people said they were using these for fish tanks? Maybe they work for that but not for anything outside of water, that’s for sure!

Holds standard air tubing very well. It sticks to the aquarium glass well and has not fell off, except when the aquarium glass wall is already wet. Then, the suction wont work. The glass must be dry for the suction to work and it can not be applied when placing it under water. It will work when the glass is dry, and then you adhere the suction cup and finally you add water to submerge the cup.

Versatile accessory you will use more of once you have tried them

Not sure what i did wrong, but....I tried to clean both surface before suck things on, fall in seconds.Tried use more suckers, fall one by one.Tried use only one, it still fall.Tried add a little bit liqid, it seens stick on, but still fall in a hour....Seriously, after test, I will never use it on anything with anything.... it is garanty to fall.The only use I can think about is maybe can put them on table to make a cup or something not easy to be overturned.All other place against gravaty, you will end up broken your display.How could this got so many good review....?

Been having trouble with existing suction cups for a while, these solved the problem. They also come in a little box for easy storage until you need them.
