Set shows little signs of use.  Case is also in very good condition with a strong piano style hinge.  Case has a pop up insert indicating this set is sterling silver.  Both instruments are marked sterling silver around the bottom of their caps.  Both feature grapevine filagree and are in good usable condition.  Each is 5" long and about 3/8" diameter.  Set in case would display well in your Sheaffer Collection.
