Iridescent helium balloons delivered to your door, our iridescent balloon in a box arrives inflated and ready to display, with nothing to blow up. The rainbow shimmer suits unicorn, mermaid and magical themes, and we box it and post it across the UK. For balloons to fill yourself, see our iridescent balloons, or pick another finish from the plain colour balloon in a box range in the wider balloons section. Match the table with iridescent party supplies. Sent inflated, it lands ready to catch the light.
