A: Hi! We can't change the delivery date after it is placed. Sorry about this inconvenience.

**Q: How do you blow up the letters? Will not inflate.**
A: Tiny straw should be included. Locate tab and slip straw between membrane to inflate.

**Q: Can these be inflated with helium?  I saw a couple reviews that said it didn’t work for them. Thanks!**
A: Yes, it can be inflated with helium of course. They couldn't float the balloons because they used just air not helium! If you not using helium then you have to use tape or glue to stick it on the wall. Thank you!

I read the description before I purchased, obviously, but I was still so shocked by the amazing value of this entire pack! I recently purchased for my cousins 21st birthday and it was such a hit! There are so many awesome items in this pack, I still can't believe how awesome and affordable it is. I'll definitely be repurchasing and looking for other packs from this seller. Note: don't pop the confetti balloons unless you wanna have a confetti (clean-up) party, haha! The rose gold colors are on-point!

    Great decorations
  

*by L***O on Reviewed in the United States on August 16, 2020*

Very fun decorations at a good price. Easy to fill (I used a small pump that I use for pool floats). And I deflated them after and will use again for another party in a couple weeks.

    Amazing Decorations!
  

*by S***S on Reviewed in the United States on December 20, 2019*

This product was a perfect way to decorate for my friends 21st birthday without spending a lot of money! Everything was perfect and it turned out awesome! The only negative I had with these products was the tiny “happy birthday” balloon letters were very difficult to blow up because they were easy to explode.
