Yea. I'd say that's a seem. That sucks.

Assuming the pictures out there are accurate, there seems to be a difference in the box construction used by different manufacturers.
From what ive seen the models made by Cloupor (such as the 101vape pre-order im in) appear to not have the seam and use a design comparable to the true Hana v3 box. It appears others chose to instead clone the Hana V2 box (i believe) which had the seam at the top.
