Member Master Caliper Giffin Grip Curved Potter

Take one measurement and you immediately have the opposite. The Lid Master does the work of two calipers with much more speed and accuracy! Plus, you can turn the screw back into the bottom set of holes and it instantly shows you how much a pot will shrink during baking. So you can make your finished work exactly to size or make lids for already baked pots. With the 12 1/2% shrink ratio, you won’t need a conversion ruler.
