Unicorn & Rainbows Party Decorations Australia | OneStopBox
Planning a unicorn party or a rainbow-themed celebration? Our Unicorn and Rainbow collection brings both looks together, so you can lean into sparkle and pastels, bold rainbow colour, or a mix of the two. It's all built around real unicorn party decorations that set the scene the moment guests arrive.
Each box is packed with everything you need for a unicorn birthday party or a rainbow party that feels properly put together: balloons, bunting, a happy birthday sign, table cover, yard sign, themed invites, games and activities, a kids' playlist, food ideas and a photo-sharing QR code. No running between five shops trying to match colours and themes yourself.
Want to take it further? We also offer a unicorn cake topper as an optional add-on, so you can finish off the cake table with the same theme running through the whole party.
Whether you're after unicorn theme party supplies or leaning more into a rainbow party look, this collection has the pieces to bring it all together in one easy box.
Pick your box, add a cake topper if you'd like one, and let the magic do the rest.
