Bottle Cap Marker

So this is a Bottle Cap Marker for any bottlecap that is 30mm Diameter.

I grew tired in the office of people writing their names on bottles and and forgetting they have an open one and then starting a different one, we throw away about 10 bottles a week because nobody is drinking them and opening a new one.

so its just a design i threw together that we can stick a name on with a label maker.

It snaps onto the cap so satisfyingly and snugly, can be taken off to open the bottle and stored
