50kg sized propane tanks for domestic and private use. 16 propane tanks with closed protection caps and 16 with removed protection caps. Can be found at almost any apartment building, house, domicile, shop, restaurant, etc. without a municipal natural gas connection. Usually two tanks are in use per household.
Will only be available in Frosted (Ultra and Extreme) Detail, because of the extreme details involved. Models appear rough in preview, but will appear smooth when finished.
