Review on 🎈 Giant Jumbo Black Number 40 Balloons – Elegant Foil Mylar Balloons for 40th Birthday Party Decorations, Anniversaries, and Events – Supplies for Women and Men by Brenda Perry

I got this for my wife as a 50th birthday surprise. Delivery without instructions, but with a small tube. Well I googled and didn't find anything with the valve these tanks had. So I proceeded cautiously. There was an obvious hole that I thought the straw should go through. But things weren't exactly easy. I knew which way the straw should go, but he didn't play along. Eventually I pierced it on the other side. It's okay since I haven't gone through the valve yet. At the end I put the tube through the valve on a balloon, inflated it, took out the tube and closed it. So I had one more try, or in this case no try. The valve of the second cylinder did not pass the pipe. I pierced it in several places. I just sealed the holes with tape and inflated through one of the holes, end of story. I don't think I'll go down this path again.
