This is part of a large selection of vintage, research grade cover slips of different sizes that i am selling - many are in sealed boxes- i have listed each type separately.
But if you buy several i can probably combine shipping to save some money - the weights do add up though sometimes.
I am also listing several GRAB-BAG LOTS of multiple open boxes of various types at real great prices.
We are listing a bunch of other microscopy stuff, new slides, cover slips of various sizes and types, used plastic slide boxes, and some prepared slides.  AND MICROSCOPES!!
