飲用杯，冷灰色，5737，0.35L / 0.50L

I was worried the lid might not seal well after my last one cracked, but this replacement cup clicks on tight and hasn’t leaked a drop so far.

The cool grey color matches my other bottles perfectly and the 0.5 liter size is just right for my morning coffee. It seals tightly without any leaks, which was my main concern with a replacement cup.

Snapped right onto my old thermos, no wobble at all. The cool grey matches the original almost exactly, which I didn't expect from a spare part.
