How it works

We've made the process of sorting out all your party supplies very easy: it's just three steps.

Step 1: Select your party box

Choose your theme or colour, box option and say how many are attending the party.

We stock all the popular children's themes, plus colours and an eco option. Choose from three different options for the box contents: silver, gold and platinum. Select your party-goer numbers in increments of 8.
