Salt & Pepper glass shakers

One of them appears to have been used - these were left at the house my mom bought - it was an estate sale home and when she moved in, she had been left with a few things the executor never sold prior to sale of the home (she had 15 dumpsters to rid of junk) She doesn't have much left to sell, except a few small things These are still in the box and only one of them appears to show very minor signs of possible Use - I think it was the salt one, but can't remember. It is not bad....But I mention every tiny thing I can see or notice Glass w/ metal screw on lids
