Not entirely sure where i needed to post this,

But, during frontier days, there was a shop that sold the crystal instrument pins.
These pins, when worn and rubbed, create a sonic instrument.
However, the pins sold, can not be worn. through an assist, i was told, yes, indeed they are supposed to be worn, and unsure why they can not be. I was suggested to post in the forums about this item, i bought 5 of them before becoming aware of the bug. Any help with this?
