Ballistol Universal Oil from Klever has been around since the beginning of the last century. Its first purpose was gun care, but it cleans, cares for and preserves all metal parts of mechanical devices, tools, door locks, etc. Ballistol can also be used for bicycle care and as a leather care product. The dot oiler enables all applications of Ballistol universal oil - as easily as with a pen - drop by drop, finely dosed on small areas or targeted only at a specific point. The spot oiler can be refilled if necessary.
