Link-O-Loon ラテックスバルーン 12インチ メタリックレッド（50個入り）

The metallic red really pops under party lights—I used about thirty for a balloon arch and not a single one had a weak seam. They held helium for a full two days without noticeable deflation.

Bought these for a birthday setup and the metallic red really popped under the lights. The 12-inch size inflated evenly, and the pack of 50 was more than enough for a full arch. Just keep an eye on little ones since the warning about choking is no joke.

The metallic sheen on these balloons is really striking—they catch the light beautifully once inflated. They held their size perfectly for the whole afternoon without any noticeable deflation. Exactly what I needed for a quick decoration job.
