Common materials include cardstock paper, metal, polyester, PET (polyethylene terephthalate), latex, and foil.
Some centerpieces come pre-assembled and free-standing for quick setup. Other kits are DIY and include cutouts, sticks, and stickers that you assemble and place in vases or flower boxes to display photos or hold small arrangements.
Paper swirls often include pre-cut holes and clear hooks for hanging; mirror disco balls typically have hanging rings for easy suspension from ceilings, beams, or trees.
They offer metallic and foil-look finishes, reflective mirror tiles on disco balls, and printed glitter or 'no-mess' glitter prints that create shimmer without loose glitter flakes.
Balloon arch kits typically list included hardware and provide illustrated instructions. Some product descriptions explicitly state the kit “includes all hardware needed for assembly and installation.”
