We have 35 new sleeves to protect items, they are new but not necessarily old - probably are about 5 - 10 years old.  They are a cross between felt and fabric more like flannel fabric.  They measure about 12" in L x about 3 3/8" in W - there is a top flap, single layer at the rounded top which measures about 2" in L.   These could be used to protect numerous items - I'm not certain what the purpose was actually for on these.
