I purchased these balloons for my daughters horse theme birthday. I had a helium tank and these inflate nicely and retain helium pretty well. I would go so far as to say these balloons are professional quality.
I liked these. I got them for an adult "country" birthday party so I was hoping they wouldn't be too obnoxious. They are a light pink and you can see the cowgirls in white. The person who filled them up for me said they were hard to tie but it wasn't a big deal for the amount I needed.
