Whaline 30 Packs Suction Cup Plastic Sucker Pads Without Hooks, Clear, 3 Size, 45 mm, 30 mm, 20 mm

These 'suction cups' work extremely well on smooth surfaces. To gain maximum adhesion they must be moistened - many people lick them before use.They incorporate a hook from which all sorts items can be suspended. I bought these to suspend Christmas lights on my windows and they did the job extremely well. Once the Christmas holidays were over the suction cups were removed without much residue - certainly no where near as much as, say, blu-tac.This set of 'suction cups' came in a variety of sizes suitable for different uses. Only the largest - 45mm - can cope with anything that is not lightweight.This is an important point. These suction cups are not designed to take heavy loads but once you receive them common sense will immediately tell you what weight they will bear.All in all these are an excellent means of hanging light weight things without glue or other adhesive.

Used these suction cups to help my homemade divider stand up in my fish tank. I put them in about 2 weeks ago and they haven't budged! No slipping, no falling, perfect. (There are extra suction cups to close gaps, doesn't reflect their suction power). I've also used these to hang items on glass etc. And they haven't budged, even with a two year old trying his best to make it!

Good to have three different sizes. Those I used are still in situ supporting items of various sizes. No problems so far.

Good amount and 3 sizes for the money - but they keep falling down, and not even hanging things that are heavy - nothing like what it shows it can support in the images.

We bought these plastic suckers to install our small stain glass projects on a window. They are perfect! Different sizes help using the best option. They are really strong and can easily support the weight of stained glasses. Delivery was quick, as planned. We will buy more in the future.

What can I say, great sucking qualities with no mess. What more can you ask for.Oh and they don’t moan either :-)

Bought these to replace old & tired suction cups that, basically, had no more suction.They arrived within 24 hours of ordering (not an Amazon Prime customer).Great collection of sizes. Ideal for hanging Christmas decorations, fit tight & stick on well.How good an advert is that ?So much better than the earache I was getting every time an ornament fell to the floor. Just buy them.

Not all suction works, few of them used but within few days fall off, need to throw away and use the new, most of them are good, still good value.
