Setup & Care
Simply step into the costume and activate the built-in battery-operated fan to keep it inflated throughout your Halloween event. The fan runs continuously during wear, so check battery levels before extended use. After the party, allow the costume to deflate fully, wipe down any dirt with a damp cloth, and store it flat in a cool, dry place for next season's festivities.

What our customers say
★★★★★
Went straight on the tree. The gold edging catches the lights beautifully and it sits upright without drooping like our old one.
★★★★★
First thing every guest picks up. The gold dish is heavier than I expected and it holds my keys and rings perfectly.
★★★★★
The pair looks like something from a gallery shop. Matte finish, no fingerprints, and the stems sit exactly how I wanted.
★★★★★
My daughter played with this for an hour straight, which never happens. Solid wood, smooth edges, no splinters anywhere.
★★★★★
Two sizes was the right call — the small one lives by the stove now. Wipes clean in seconds and no staining so far.
★★★★★
Silent movement, which was the whole reason I bought it. Looks far more expensive than it was.
★★★★★
The glow is soft enough to leave on overnight and the numbers read clearly from across the room.
★★★★★
Mounted under the cabinet in five minutes and it hasn't budged. Tears one-handed exactly like it should.
