I've got 40 of them. All are in used but good condition. And they're cheap. $1 each plus shipping. And... A 3 1/4 x 4 1/4 film pack that has some film in it. It's a little rough -- some external corrosion. I've not opened it to check the inside. $2 + shipping. And ... 10+ extra dark slides. All for $5 + shipping. PayPal OK.
