Link-o-Loon 橘色氣球 - 12" 乳膠 (50入)

These inflated to a perfect 12 inches and the latex feels thick enough to survive a few bumps before popping. I used about 30 of them for a birthday arch and none had any weak spots.

We threw these in the cart for a last-minute birthday arch, and the orange shade stayed bright even after a full day in the sun. The latex feels sturdy enough that a few accidental squeezes didn’t pop them, which is a win with kids around. Just keep the uninflated ones out of little hands as the war

The 12-inch size is perfect for creating a balloon arch; they’re easy to inflate and hold their color well. I’ve already used half the pack for a party and none have popped yet.
