Paper box that transforms from an envelope (SPM ver.)

SPM version of the "paper box that transforms from an envelope" presented at UNBOX Vol. 2 presented at UNBOX Vol. 2.

The "paper box that transforms from an envelope" is thin and thick, a contradiction that has been realized.
It can be used as an envelope when you want to put thin and flat things in it, and can be used as a gusset by changing the fold line.
By changing the fold line and adding a gusset, it can also be used as a box ideal for storing small items.
The SPM logo is foil-stamped.
