Link-o-Loon 黑色氣球 - 12" 乳膠 (50入)

These inflated beautifully with a hand pump and held their color really well for the whole party weekend. I was worried about them popping easily, but they lasted longer than I expected for a pack of 50.

These inflated into a solid, consistent 12 inches with no weak spots or thin patches in the whole 50-pack. The latex feels a bit thicker than the cheap party-store kind, so I'm expecting fewer random pops before the event even starts.

These balloons are a great value for a party pack; the latex is thick enough that I only had a couple pop while inflating. I used them to make a balloon arch and the black color looks really sleek against any backdrop.
