is a set of 15 reproduction German WWII aluminum rivets that are to be
used to attach the helmet liner leather to the inner band (see the
second picture). They are European made and just like the originals. The
number of rivets needed on each liner depends a lot on the size. For
the size 61 liner (one of the largest made) uses 13 rivet so you have
two extra on top of that. It is only $2.00 to ship these rivets anywhere
in the world.
