Milligan Bio’s Pen. Oil is made from canola-based products which makes it renewable and environmentally friendly. Made right in Foam Lake, SK, we turn canola by-products into this unique and efficient product. The uses are endless, from the shop to the house! Pen Oil gives you the best of both worlds, it is non-toxic, fume free but tough enough on rust and grease. It can be used anywhere that lubrication is needed, or corrosion is a problem.
