20 Balloon Self Seal Valves with Ribbons For Use With Helium Only

Not sure if it was the valves or the balloons but they deflated in 12hours whereas the self sealing balloons are still up 3 weeks later

Helium leaked out. Balloons didn’t last more than a few hours before dropping. Fortunately I was able to top them up for the surprise but sure enough, a few hours later, all the balloons dropped again.

Wanted party ballons and these valves complete with strings were just great at a great price.Helium balloons have a limited life so blow up as late as you can!!!

didn't use many them in the end not very user friendly and the only balloons that had the valve soon went down. Although to be fair it may well have been user fault and not the valves.

Great idea for filling up balloons quickly but some of the valves had sharp bits of plastic on the balloon sides which meant a few balloons were left with holes in them (about 1 in 10)

Worked well when used with helium balloons, no complaints

A child's birthday party required the purchase of a job lot of balloons and hence valves too. They work very well and can be re-used, if you are into balloons in a big way. Good price, work well, recommended.

It arrived on time very nice.
