Six double walled borosilicate cups. The inner and outer walls are separated by a sealed air gap, so what is inside stays hot for longer and the outside stays cool enough to hold without a handle. Tea appears to float in the middle of the glass, which is the reason most people buy them.
Features
- Double wall construction with a sealed air gap between the layers
- Outer wall stays cool enough to hold with a full cup of boiling water inside
- High borosilicate glass, which takes thermal change without crazing
- No handle, so they stack close together in a cupboard
- Set of six at 250 ml, enough for a table rather than a person
- 250 ml each, six to a set, enough for a table rather than one person
