Is it permissible to name a box containing a rosary "Pendulum of Sins" and distribute it to people for the purpose of glorifying God?

Encouraging people to perform tasbih (glorification of God) and istighfar (seeking forgiveness) by inventing permissible means is a praiseworthy act, and there is no harm in it. However, performing tasbih with the hand is superior to using a rosary (misbaha), and there are other means more beneficial for calling people to Allah.
