I Will take 2 of each whale bits. What is the mystery box?
There is a Mystery Note.... the Mystery note series was meant to incorporate new tech into the notes.
Each one produced, Polymerbit has tried new things such as a window/clear strip on Mystery Note 2.
Mystery Note 3 shows off the integrated hologram strip on the left front side
Mystery Note 4 showed off their new intaglio printing method
Will PM you about the other notes
