スプリングフラワーズ チリーズ 保温カップ

The flowers printed on the cup have stayed bright after a few weeks of hand washing, which I didn't expect. It sat in my car's cup holder all day and my tea was still warm when I got back.

Took this on a four-hour train ride and my tea was still properly hot at the end, which I honestly didn't expect. The lid seals tight enough that it didn't leak sideways in my bag either.
