I love it! My sister love it!Excellent balloons for a glow party. Had about 5pop but it comes with over 200 balloons so didn’t use them all. Works great with a black lightI purchased these balloons and some 9 in ones from my local super grocery store to fill in with different sizes. They all inflated to about the same size. If blown up any bigger they got so thin they burst just by hitting the floor after I tied them. Several in the pack had extra thin spots and slowly leaked before I was done blowing the whole lot up. Their reaction to the black lights was pretty amazing, though!The balloons were good colors besides the pink and purple ones. They were somewhat transparent and see through so they didn’t have a bold color next to the other neon ones. I wouldn’t haven’t gotten them if i knew they would be transparent.We used these for a 2 year old’s glow birthday party. Some had holes but must were fine. They hung in there like any average balloon and did glow in the black lights.These balloons had a pretty heavy smell when I first unpackaged them, but it dissipated quickly. Easy to blow up (I used an electric balloon inflator) and after 6 full days, they’re still inflated just as well! Made a garland out of these. The greens and yellow were the brightest under the black light, but pink was my favorite. I do not recommend inflating these all the way though - they felt like they were going to pop easily if I did. I would say about 75% full is the best for these (which also give the best ‘round’ shape, anyway, so that worked out well for me).Glow in the dark particles came off balloon while inflating. The purple balloons did not hold air over night. Students played with them at black light party. It was a hit!!Balloons didnt glow under black light. Couldn't inflate very much so Balloons were undersized. Also inflated with Helium the balloons popped really easily. Do not recommend.
