Bunch O Balloons has gone from just water balloons to air/helium filled party balloons as well. You have to purchase their portable electric air pump to inflate the balloons. Each balloon is attached to a plastic straw that is manufactured into each balloon. The balloons are grouped into sets of 10 balloons. There were some balloons with holes and defects that prevented them from blowing up, so don't count on all 10 balloons working, yet the majority of the time there were 10 that inflated (some smaller than others). It's fun and makes for easy party decorations, yet I think I prefer spending the extra time blowing up balloons by mouth. It's more reliable.Love these balloons so freaking much. We use the bunch-o-balloon brand inflator for air (or the attachment that comes in the box to do a few helium ones with a home helium canister) and then hang the whole bunch using the inflator tubes as a tie. It is the easiest balloon decor possible - 5 minutes start to finish. Can’t love them more (unless they were cheaper)!I hate paying this much per balloon until I try to use the normal ones. Then I would pay the premium so try to remember that when checking out. You are not really buying balloons, you are paying for them to basically be pain and stress-free to use. We all have too many things to do when you are getting ready for a party so anything that can help is worth it.WORTH EVERY PENNY!Bought this for my sons 3rd birthday. I’ve used this style of balloons before used the brand inflater and the balloons were popping half filled or just not filling and if they did fill the rubber by the stems were old that they ripped and caused the air to leak out. I bought multiple boxes and had maybe 10 balloons actually stay filled with air. Will not purchase this product from this seller again.Used these for an annual office event. Every year we have about 4 people helping to blow up and tie the balloons with the helium tanks. We usually lose a few and they always get tangled up together with all the strings. This year my 13 year old helped me and he blew up over 100 balloons and it took maybe a half hour but that was due to tying them to the balloon weights. One good thing to note is you can buy these packs and there is an attachment piece inside every pack of balloons that will allow you to use a helium tank. Would highly recommend and will buy these every year going forward for this event! Arrived on time and exactly as described.These were perfect! I couldn't find green in any store and needed these for a party.Love the bunch o balloons, blew them up for a party and after 4 weeks they are still fully inflated , lost no air at all, I highly recommend them.I love this product more than I can explain! Quick. Like a snap! I have no time and don't want to spend tons of money on helium. This is the great alternative I think ever.Absolute.rubbish.almost impossible to blow up so they went in the.binI’ve bought so many packs of theseWere great value for money went up easy and lasted days
