Individual packs contain 5 blades
20 packs of 5 blades each = a bulk pack of 100 blades
I used these in combination with a 40's style Superspeed and they just didn't work for me. I gave up after two mediocre shaves. Of course, with blades, YMMV. Went back to my preferred Parker Premium Platinums.
Love this blade, in my top 5. Offered a BBS using my Merkur 34c.
Not crazy about these blades. Got in a sampler pack and can confidently say they are one of the least sharp blades I've used. Do not offer a very close shave. Have a fairly slow-growing beard that only needs to be shaved at most every other day normally and with these looked and felt as though needed to shave by the time I left work. Inexpensive, but better options at the same price point
