Lisle is the maker, but they are sold thru many outlets and stores. You will often find them in the REAL parts stores I talk about. You know, the stores that supply parts to the shops in town, not the "McParts" stores you find in strip malls.
I have NEVER been disapointed with one of their products, they are pro used, and top notch.
i buy lisle at sears, great stuff
