You must have been one of the first to do it!

I've had mine for a similar length of time. Friend ran a few piercing/body mod shops in the UK and had just gotten them in. A few friends got them at the same time though most eventually had them cut out. Mines still there it's a fun party truck these days I never actually used it for anything.

Had to convince a company we had an Alpaca farm and needed a few tags to test with our livestock. They sent me a few EM4104s.
