Yesterday I ordered from PAA their 400 Switchback brush handle (their clone of the Rubberset 400), 24mm synthetic knot for the handle, a Super Speed t shirt and 3 packets of Gillette Super Thin blades. I also ordered from Amazon a Loctite 2 in 1 epoxy to mount the knot in my new brush handle.
I have cases for my Schick I2 razors, but not for my I1. I found this and it was at a great price................
