Tulpen reiskop van rijstschil

Didn't expect a cup made from rice husks to hold heat this well — my coffee was still warm two hours into my commute. It's light in my bag and has zero plastic smell, which was my main worry ordering it.

The rice husk material feels sturdier than I expected and it doesn't have that weird plastic smell new cups usually get. Only thing is it holds heat for maybe an hour, not much more, so it's fine for my short commute but not a long drive.
