AAvK notes:

piece for hand stropping. Supposedly this is very thin leather (5/64 to
5.5/64)
that is extremely tough, these pieces are "vegetable tanned" (veggy oil?).

Not oil. Vegetable tannins. Actually the only way leather is 'tanned' which is
the process of changing it from raw skin to leather.
