I'm curious what is used for keeping razors in between use. The options I am aware of is: 1. Box razor came in 2. leather sheath 3. sack ups razor sleeve or similar 4. I saw one that was similar to the sack ups but had silver flecks in the fabric. Other ideas?

What are the opinions? I like the idea of leather but have read that it can promote rust/tarnish of the razor.

Many thanks!
