Great birthday gift

Our niece loved it. WOW was repeated numerous times. We gifted this with a mat so that she could lay it out and play nail studio without making a mess.

Nice product

This was used for a themed birthday party, and it looked really nice. The balloons were strong, and there were barely any pops.Just be aware that the kit does not include the gold background.
