For the last time these are not laser engraved. They are laser etched. Laser etching is a superficial process and not anywhere near as durable as engraving. Save your money for REAL engravings.
It is done with a laser engraver. Unless you have a source that can actually engrave on metal at the prices he is selling it at please share. Other then that he is selling a product that is supporting bitcoin structure. Why would you try and hurt a merchant that has a good idea by telling people to save money. Is that how a recession is started by people not wanting to spend money? Great idea for the cards.
You don't have a clue about lasers. And my point stands these are being labeled as laser engraved, which they are not. They are laser etched which is a superficial surface only marking. I'm not supporting the community by telling the truth about a product marketed as something it's not? I'm sorry for telling the bitcoin community this isn't the durable engraved product they think they're getting.
