this is propably nothing to worry about but I recently purchased 3 trezor devices, 2 of these had the usual tear to the box because of the strong glue, the third trezor device however the glue cleanly only was left on one side while the other side had no glue or tear marks.
I did use a knife to open these 3 as I know the glue is strong/sticky.

I'm assuming this was either lucky or just bad quality glue and nothing I need to worry about?

as in this review 3rd picture has tear visible to the box, on one of my device box there was no tear at all and all of the glue stuck to one side of the box while the other side was completely free from glue / signs of tear.

edit--> as far as I can tell all 3 had the holo sticker in 100% mint condition, plastic wrap, although the plastic wrap had holes in corners on one of the boxes but this is due to shipping I assume.
