OMTech Laser Marking Powder, 4.1 fl. oz. Metal Laser Marking Fluid for CO2 Laser Engraver, High Contrast Laser Marking Ink for Metal, Laser Black Ink Laser Ink Agent for Aluminum Stainless Steel Brass

Très bien

This is a game changer. I have used the spray cans and love the result. But it's pretty easy to use more than is needed. This is a much more manageable delivery than the aerosol spray. It's neater and easier to control the application. It's more economical. Does the same job, just cheaper and neater!

The listing says Laser Marking Fluid, 4.1oz. However, this is apparently to indicate it MAKES 4.1oz of fluid, when ethanol is added. Other listings are explicit that it's powder and fluid must be added, never mind that they generally use alcohol which is a lot easier to buy. Don't get fooled like me - this is 40g (1.4oz) of POWDER, and requires ETHANOL and not alcohol. Don't buy this if you were hoping to avoid the hassle of finding alcohol/ethanol and mixing the fluid!

I have always used cermark for my laser marking. I had ran out of it and needed to order more but was in a time crunch found this and it was here the next day got my orders done and was very happy with the results. I will be ordering again.

Quality Product.
