Just picked one of these up. I don't have a picture at the moment, but I thought I'd send out a heads up. It is a metal case with a push button opener that holds the mini Bics. If weight is an issue, it might be a bit hefty. If you carry your mini in a pouch or kit, it's probably too bulky. However, I just started carrying a mini Bic in my pocket, so I thought this would be a great way for me to carry it, and not have to worry about leaking the butane out, yet not having to rubber band or toothpick the Bic to "lock it out". I got mine at Target for $2.99...that's the holder and two minis.

Are they water proof/resistant or just covers?

It's just a cover, but it works pretty well. At best, it'll probably only keep out a light sprinkling of water.

It also has a lanyard/keyring hole in the cap, which makes it a convenient carry.

I have one of these, and with the exception of weight, I like them.

I have one also.... I like the fact that you can put it on a key ring or on some paracord.
