Started out with me jokingly threatening in taking my faction mates kneecaps for various silly reasons which then turned into them giving me bones as offerings. All those who donate bones are deemed as Honorary Boner Donors (bone being autocorrected to boner one day and stuck as a joke).
Also recently started to collect Model Spines and Dentures.
Great place to find items for a good bargain. The owner is very friendly and takes the time out of their day to reach out to their customers. 10/10 would definitely recommend especially for new players just starting out.
