Harry Potter Zweinstein Huizen Ronde Folie Heliumballon 46 cm / 18 in

My son’s face lit up when he saw this balloon—the double-sided Hogwarts crest print is way clearer and more vibrant than I expected. It inflated easily and has stayed afloat for days without any trouble.

The metallic foil is really nice and shiny on both sides, and the fact that it self-seals made filling it a breeze. My son was thrilled to see the house crests printed clearly on each side for his party.

Bought this for my niece's birthday and the double-sided print is a nice touch since the design shows from every angle. It sealed itself right after we filled it with helium, no tying knots or worrying about it deflating mid-party. The 18-inch size felt just right for a table display over the cake.
