I have been using the Bodum double walled cups, but they are thin and do break easily. Down to my last cup of the set.
Yesterday, I was in Sur Le Table, (where I bought them originally) and they are now carrying the Heckles double walled cup. They said they switched to the Zwillig/Heckles cup, that they were stronger and less prone to breakage, than the Bodum. The still carry both lines in other products, just not the cups. So, there may be some truth in what she said.
The Zwillig cups are larger 12 oz., and clunky looking with very thin uncomfortable handles. The Bodum had nice thicker handles and a 10-oz. cup, which is a good size.
Double walled cups do keep a cup hotter, longer, especially when pr- heated with a splash of hot water. They both are a bit pricy at 12-15 dollars, but worth it. Mine have lasted almost 2 years and we hand wash our cups, broken 3.
I did find the 10 oz. Bodum at Crate and Barrel if you want to hold one before purchasing.
Has anyone used the Zwillig/Henkel’s cup, and do they hold up well?
