I ordered retainers the other day.. got them from
summit(it was a drop shipment).. ordered 7* 1.500
with a step.. I checked them out today and see that
they are 1.437 dia.. these are packaged as a 768-16
which says 1.500.. I think they have the wrong ones
in the package.. gonna send them back.. but you
know how shipping is during this time frame
