I checked that out, and aside from the fact that it comes in "extra
fine", etc. instead of numbered grades, the description reads just like
Liberon. Wonder if Liberon and Lee Valley get their stuff from the same
manufacturer?

We Canadians know what one or two side by side zeros are, but more
than two adjacent zeros such as 0000 grade has us totally confused.
