Good

### ⭐⭐⭐⭐⭐ Genius idea of glass with silicon lid
*by S***P on 26 July 2025*

Love it. The silicon lid fits on the glass perfectly and it looks beautiful and I can have my hot or iced drink in it

### ⭐⭐⭐ Not bad
*by A***D on 13 November 2025*

The inner seal was not in perfect shape, looks like it was pre-used. Also the grey lid slips off especially if there are hot drinks in the cup because the vapor pushes the lid until it slips away from the mouth part.
