Contemporary artist Damien Hirst is anything but scared of death. A list of his collection of artwork reads like a kunstkammer of mortal symbolism: platinum skulls, visceral depictions of human organs, dead animals, and so on. So his recent collaboration with online luxury retailer Just One Eye and Mary Kate and Ashley Olsen’s fashion line The Row produced, unsurprisingly, a twisted take on backpacks and some of his own masterpieces.

Hirst designed a $55,000 black patent leather Nile crocodile backpack studded with with numerous unusable prescription pills that will be available in limited quantities beginning Dec. 12. Other designs have small gold or multicolored dots, large gold or multicolored dots, and black and grey pills. Hirst will determine how much of the proceeds from sales of the 12 bags will be donated to UNICEF.
