Note!
The knob should be turned only in one direction (as in the photo) in the opposite direction you can break the brake (that's why there are more of them on the tray for printing - photo).
To remove the used toothpaste, squeeze the locking butterflies with your fingers (as in the photo).
The eyes and antennae should be glued carefully so that the person using the toothpaste squeezer doesn't get upset if something falls off :-).
We don't give the printed toothpaste squeezer to play with, it should serve its intended purpose.
