These are "Milwaukee" heavy duty tumblers.  A bit pricey but the client who requested them was so "gung ho" about the fact that I could engrave them, when I told him what I would charge, he didn't think twice and instead answered, "Great, how soon can you get them done?"  I told him 3 days (mainly because I wanted to buy an extra one to test on...lol).

Included in the file is the image that I used, the text and the "test grid."   I used the RA2 Pro /Chuck and made sure I ran "framing" before engraving them.
