Pouch 'em and stack 'em. If you are looking for a travelling solution or something to use to protect your razors from bumps and scratches these might be a good option for you.

These are pretty compact, so make sure your razor is not longer than 100 mm, otherwise some bits will stick out or the pouch will look askew when in the closed position. Razors with handles in the range 10 to 16 mm in diameter qualify as candidates for new RDP-accommodation
