A 15" medicine cabinet was designed to fit between standard 2x4 studs on 16"
centers. The blades dropped into the inter-wall space created by those
2x4s. A quick calculation for a medicine cabinet at 5' high, 15" wide, 3.5"
deep shows a space of some 3150 cubic inches. Assuming the blades were
about 1" x 2" x 0.005, this gives a blade volume of.01 cubic inches. You
could drop 315,000 blades into the slot before the space filled up. If you
changed blades every other day, you had a little over 1700 years of
capacity.

The medicine cabinet in my childhood home had such a slot. Back then,
a razor blade was only good for one or two shaves. My father must have
dropped thousands of blades down that slot over the decades. Always
wondered where they went.
