Hey Sigman,
I was wondering the same thing.
I checked out the web site and from the
pictures. It's a device that you can change
out different guage circumference to punch out
holes in ( I assume ) plastic and I'm sure other
materials. I use to run a leather factory.
And we had punch sets with variety of sizes to
punch holes in leather. That's what I can make
of it. Cheers mate!!!
