These cute tiny cups are a pleasure to use and look at
This little cute cups was designed in double wall and thus I have no worry on direct hold it to drink in a hot tea.
Because of it is a clear glasses, is really enjoy to see the beautiful color of the tea espeacially the Raw Pu'er tea which have the beautiful amber color while drinking.
I was gifted 4 sip easy cups and I like using them. Clean look with a design that makes sure I don't get burned by hot drinks.
