藍色與灰色雙層生日快樂氣球套組- 5入

The grey and blue combo looks even better in person, and the double-layer effect gives them a nice depth that photos don't quite capture. I blew up a full set for my son's party and they held up the whole afternoon without any deflating.

The double-layer design really makes these balloons pop—the blue and grey combo looks so much more polished than solid-color ones. They held their helium well for the full party without sagging, which saved me from having to re-inflate anything.

I blew up five of these for a party and every single one inflated perfectly without any weak seams. The double layer gives them a nice rich color that really pops against a plain wall.
