I bought these to personalize with laser etching. I haven't done such yet, but I have little doubt they will do well. The finish is somewhat coarse. However, it does help with the grip. The cylinder is a bit large for small hands. Nonetheless, it does a beautiful job of keeping things cold and hot; A there. One of the nice things about such a design is that the double walls prevent sweating. They are very attractive and should be marvelous for personal use or gifts.
