For those who can't decide which size is best. 50~5kg sized propane tanks for domestic and private use. 56 propane tanks in all available sizes and forms. These can be found at almost any apartment building, house, domicile, shop, restaurant, etc. without a municipal natural gas connection.
Usually these smaller ones are popular at mobile food stands (yatai).
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.
