Very cool.  I was wondering how many years it would take for someone else to do an engraved product with vanity addresses.  Looks like the answer was 9. 

Kudos for creating this product.  I've very happy to see it.  I know a lot of work goes into producing such items and I think your price point is reflective of that.  I hope that as more items like this come to market, it highlights some of the OG products for the bargain they are.

Good luck with this!  Keep up the great work!  I look forward to seeing how buyers track the ROI over time and how their opinions of the product are affected as a result.
