A man and his nephew in California got a little more than they expected when they won an auction for an abandoned storage unit.

At Cubesmart in Rancho Cordova, units are auctioned when renters default on them for longer than 45 days, according to NBC affiliate KCRA. Some people buy these units and resell them for a profit.

The two men won one of the units with an $80 bid, according to the station. However, it contained a box full of hazardous, old-fashioned equipment used to make meth.

Narcotics officers told the station that the material was so toxic, hazmat specialists had to be called out.

Sacramento County Sheriff's Department detectives are not sure if the lab was operated on site, but they are now looking for the original owners of the unit, according to KCRA.

A message for comment left with Cubesmart was not immediately returned.
