What I love about these balloons is that you can either use these with just regular air or helium. I only know this because with 1 of the balloons, I was able to fill it with regular air with an electronic air pump. I used it for a table decoration and it came out really good. Even with using tape and balloon dots, I found that if I have to stick and unstick the tape or dots, it doesn't remove the picture or paint that is on the balloon itself. Not to mention, the balloons don't tear easily either. There is an area on top that has a tag that allows me to even hang these if I want to. The other 3 were filled with helium and again, I was able to fill them without any issues. Really cute balloons and absolutely adorable too. The colors on these is really bright and vibrant too.
