Review on TONIFUL Black Happy Birthday Balloons Banner – 16 Inch Mylar Foil Letters | Reusable Eco-friendly Material | Girls, Boys, Kids, Adults Birthday Decorations & Halloween Party Supplies by Jason Dinh

I was totally impressed with the quality of this balloon set. I found it easy to inflate, the size was perfect for our needs (about 14 inches when inflated), the thickness of the balloons was good, and each letter was well thought out. Each letter had a series of tabs in the right places through which the tape could be threaded to hold the letter in place. For example, the letter "H" had 4 protrusions, one at each end of the letter (see image). I blew them up and hung them on a wrought iron fence for an event last week and a week later they are still fully inflated (kept indoors after the event). I bought letters for my son's name from a local party store (Par **City) and these letters from Revain are of a much better quality. Emails from elsewhere didn't have enough tabs to keep the letters stable. I would highly recommend this Revain Happy Birthday Balloon Set and will definitely be purchasing again. I continued to store the balloons indoors with air and finally deflated them with the straws provided in 3/2021 to use again! (One less to harm the environment and also be frugal! ;)
