Personalised 3D-printed keyrings & party favours in Richmond upon Thames

Custom keyrings, made to order

Every keyring is 3D-printed to order in tough, lightweight PLA — a plant-based plastic that stands up to everyday life on school bags, keys and pencil cases. Pick from our designs — octopus, panda, rubber duck, orca, hexagon and more — or tell us your own idea and colours and we'll print it just for you. Keyrings start at £3.50, and 3 or more come with a little discount.

Party-bag favours for Richmond birthdays & school events

Planning a party in Richmond, Twickenham or Teddington? We make personalised party-bag favours that are cheaper than the plastic tat that gets binned by bedtime — and reusable, so kids actually keep them. Match them to your theme and colours, with names if you like. Priced per batch by design and quantity — message us with your date and numbers and we'll sort it.

Free local collection across the borough

Because we're based right here in Richmond upon Thames, local orders get free collection — we hand them over near you, no postage needed. Further afield? UK postage is a flat £2. You'll also find us in person at local school fairs and markets around Richmond throughout the year (we run a fun guess-the-print-time competition at the stall — our Godzilla took a whopping 778 minutes!).
