Does not have a normal size hole to inflateJust as described. True to color balloons are durable none have popped while inflating and still holding strong the next day would totally recommend and can’t beat the price. Have not tried it with helium.There were about 6 balloons that had holes in them that I couldn't use, and a few that randomly popped without warning awhile after I blew them up, but the rest were great. I aired them up in different sizes, and used them to create "clouds" at the baby shower I hosted. The ones that popped, did so after I had made the "clouds", which made them look less "fluffy", but they still looked good. The ones that made it through were strong enough that they didn't want to pop after the shower was over, so they were nice and sturdy. Overall I'm happy I got them.Great price for the amount of balloons you are getting. These balloons are really good quality. They lasted all night for an event. We blew them up using a balloon blowing machine and they got really big. Kids even grabbed some and ran around with them and took a LOT for them to pop. They look really nice blown up and have a nice shine to them. Definitely great and can be used for many occasions.Perfect shade of blue for my event!!!Can’t wait to use them Friday
