I’ve never purchased any kind of glassware that’s double walled, but I love these! I recently purchased an espresso machine and these truly do keep the beverage warm much longer than my regular stoneware mugs. The handle is large if you have bigger hands, and they look great! The beverage looks like it’s suspended in mid air which is pretty cool and unique. While these are certainly pricier, they are great quality and I highly recommend. Do not pass these up.
