Well, after quite some time and a lot of use, I threw this cup away yesterday.
The plastic absorbed the jasmine scent, and started releasing a plastic scent, so everything in the cup smelled and tasted like plastic jasmine.
I’ll miss it, it was about the perfect size and shape and form, but I am leery of heating plastic these days anyway. I brought my glass double-wall bottle from Adagio (the activiTEA) to work to replace it, we will see how we get along. It’s almost too skinny – I don’t like it when I can’t really comfortably get my hand in a glass to clean it thoroughly.
