Invite disco fever into your home this Christmas with our Mirror Ball Ornament! This unconventional Christmas tree ornament is perfect for those seeking not so traditional Christmas decor. This disco ball ornament has a styrofoam ball center and is covered in cut-out mirror squares. The 2.5cm size had a silver string attached to it for easy hanging, while the 20cm and 30cm sizes have a keychain-like loop attached to it.
