An ordinary medal vs. our medal
The weight of metal. Design POWERED BY TECHNOLOGY.
A classic medal is a piece of metal, wood or glass — an expensive mould, one colour and thousands of identical pieces. Our unique medal weighs as much as a metal one, yet it’s better: neither shape nor colours have any limits.
The past
An ordinary medal
- Metalexpensive mould, long production
- Engraved woodone colour
- Plexiglassflat shape
- Moulded plasticevery piece identical
- Glassfragile
- Acrylicno relief
- Chipboardcheap, and it shows
- Flat and usually just one colour
- Expensive mould; production in Asia takes around two months
- Thousands of pieces with the same motif
The future
Our medal
- 80–100 gthe heavy version feels like metal around the neck
- Any shapeand up to 16 colours on both sides
- No mouldhundreds of pieces printed by the next day
- From €1the price of a cheap wooden medal
- 2 PET bottles from the oceanin every oPET medal
- Every one an originalno design made twice
This is what our medals look like — every one different

Ocean PET · sustainability
Every oPET medal = 2 PET bottles fished out of the ocean.
The bottles are fished out of polluted seas, desalted, dried, sorted and turned into filament for 3D printing. We use it to print medals, trophies and merch — the first and only ones in the world to do so.

Officially certified material
We source our material from the Swiss company #tide, certified under Ocean Bound Plastic and the Global Recycled Standard — every kilogram is certified and traceable to its origin. With every oPET order you also receive a CleanOcean.Run certificate showing the exact number of bottles in your medals.
