Onyx Black Helium Ceiling Balloons x 25

Fill your ceiling with 11″ biodegradable black latex balloons on either 50 cm matching satin ribbon or 2 m curling ribbon, with optional satin bows for extra flair. They arrive helium‑inflated and treated with Hi‑Float (to last up to a week), along with extra balloons in case of deflation. Orders must be in multiples of 25 (e.g. quantity 4 = 100 balloons). For dense coverage use about 9 balloons per m²; for a more scattered effect use about 5 per m². Store them at room temperature to maximize longevity.
