Questions ❓

The stuff people usually ask us

How long does a 3D print take?

It depends on the size! A keyring prints in under an hour, but big detailed models take much longer — our Godzilla took a whopping 778 minutes (12h 58m!). See the proof on our Competitions page, or read our full guide on print times.

How do I order?

Add the keyrings you love to your basket and pay securely by card. At checkout you choose free collection (we hand over locally) or £2 UK postage. For party favours or custom designs, message us on WhatsApp or use the order form.

Can you make a custom design?

Yes — custom orders are our favourite! Your idea, your colours. Tap "Contact us to discuss" and tell us what you're after.

What are the keyrings made of?

Tough, lightweight PLA — a plant-based plastic that's great for everyday use on bags, keys and pencil cases.

Where can I find you?

We're based in Richmond upon Thames — serving Twickenham, Teddington, Kew and East Sheen — and sell at local school fairs and markets, with free local collection around Richmond. Message us to see where we'll be next!
