Frequently Asked Questions

How many kids does this party box work for?

The Medium box is ideal for parties of 10 – 20 kids in a medium to large room. It's designed to transform your space into an amazing themed party, with matching decorations that bring everything together. Want to complete the look? Add themed tableware, themed extras and party extras when you build your box.

Will my box arrive in time for my party?

We recommend ordering at least 3 weeks before your party. This gives plenty of time for delivery, sending invitations and getting food and activities organised.

Party coming up sooner? Give us a call before ordering and we'll let you know what's possible!

What free extras do I get and do I need to print them?

After you add your decorations box, you can add a custom invite and themed games for free in the next step.

Custom invite: we send you a short survey to collect your party details, then design your invite. You get unlimited free revisions until you’re 100% happy.

Themed games: we send you a link to download your games, plus a bonus pack of extra games. They’re digital PDFs you print at home, split into printable sheets and answer sheets.

Playlists and planning: your playlists open from QR codes that link to public Spotify lists, so there’s no setup. The checklists and run sheet are yours to print or use on your device.

Can I customise my box?

Absolutely! Your Medium Party Box is already curated with matching decorations, so the hard work is done for you.

Want to make it your own? Choose from themed tableware, themed extras, plus a range of fun party extras in the next step. Everything is designed to work with your theme, so you can add what you want without the headache of planning it all yourself.

How long does it take to set up my party?
