Travel Size Salt & Pepper Shakers Glass w/ Metal Holder Vintage Picnic Lunchbox

Vintage travel size salt & pepper shakers are held together by a metal collar with hinged lids. The brown plastic (Bakelite?) lids unscrew from the glass shakers to remove from the metal collar. Each shaker is approx. 1 3/4" tall including lid x 1" at widest point. Total size (when in metal collar/holder) is 2 1/4" long x 2" tall x 1" wide. Pre-owned vintage condition: Metal hinged lid/holder has rust in multiple areas as shown. Brown screw-on lids and glass shakers are in good condition with some surface marks from use/storage.
