Not loosing this one
Love my trusty paint pen.
I have never been a fan of those cheesy wine glass tags. Although in this case - having a stemless glass makes the point mute.
Everytime I have a party or Social - the paint pen makes an appearance without fail. Some people's inner child surfaces, and with it comes tiny sketches or just a simple initial. Matter not, just as long as they have the eye on the prize .... Then, happy campers all round.

No harm, no foul!
