Ok I wrote El Mar Inc.

You can be assured that the tweezers sold at the www.slivergripper.ca web site are authentic Uncle Bill's Sliver Grippers. slivergripper.ca purchases the Sliver Gripper directly from us (...)

So yes those are the real McCoy. Sometimes I think I'm a bit paranoid... Paul Winchell from his office in Québec offers direct web sales of Sliver Grippers only, that's why they are less expensive than at Lee Valley or something like that.

Thank you
