Hi nikola, it's very interesting! I like the look of it, but I wonder how comfortable it would be to actually drink out of it... Like would it be sort of off balance when you took a drink? Hard to know I guess without actually using it.

Thank you Michael for your feedbacks and critics.I see now,where is the problem.I fixed the problem with handle position,but I have to cut also my concept and create better shape for the mouth.This will brake my continuous triangular shape,but I will get the function.I will update it as soon as I fix my design.
