密封環隔熱玻璃，銀色，0.94 L

The sealing ring fits perfectly and creates a tight seal, no more leaks in my bag. The silver glass insert is sturdy and easy to clean after a long day. Exactly what I needed to replace the broken part.

My old thermos finally stopped keeping coffee hot, but this replacement glass fit perfectly and brought it back to life. The silver finish matches the original exactly, and the sealing ring creates a tight vacuum seal again.

I was worried the replacement glass wouldn't sit flush, but it dropped right into my old insulated pot with zero wobble. The sealing ring fits snugly and I've had no leaks since.
