Once - quite a while ago - laid out laid out on Habré a couple of posts in which it was proposed to guess the appointment of a strange kind of stationery. In connection with the discovery of new artifacts, I continue.

Purpose of object No. 3
Nobody will guess the purpose of the third object. It is impossible to guess, in my opinion, especially since the Writing controller is poorly translated into Russian. Although in general it is clear: we have a finger clip in front of us while writing texts.
If you look closely at the picture (the quality is traditionally unimportant, unfortunately), you can see two small plaques on the index and thumb.
