Regarding the products themselves, I'm kind of 'meh' on the prints. Both turned out much smaller than I was expecting, but that may just have been the angle of the shots for the website.
I tried to compare them as closely as I could to the actual sizes.

I still like them though, and they're a nice addition to some of my glassware.
EDIT: Also 'meh', the print goes nearly transparent when the glass is chilled / filled. Not so bad in this pic though, but a flash helps: https://i.imgur.com/Dp92yUV.jpg
We can gladly make them larger for you if you'd like. You actually got different then the pictures thou because the pictures were an acid etch using a cream. The items you got wound up being a higher quality sandblast. Contact me for options, and I'll gladly rectify things if you are not fully pleased.
Thanks and we hope you enjoy them still!
