BESTFIT stems (2) for Fleurier caliber 350 - new in envelope

Two BESTFIT stems for Fleurier caliber 350, 380, 390, Rolex caliber 390, new in unsealed envelope. The package contains two stems even though it says 1/4 doz (which would be 3), presumably one was used which is why the envelope is open. I specialize is hard to find watch parts so I usually have whatever you might need, all watch parts are unconditionally guaranteed and offers are welcome. Images do a suitable job of representing the item.
