I was skeptical at first because of the price, but you really don't use much at all. I started with the 0.125L can (4.22 oz)
for about $20, lasted forever. Bought a second and am about 1/2 way through.
Finally got a 0.75L can to go "all in" from Klingspor when they had it on sale.

Some info on these hard wax oils.
