I don't know, I got mine from an ebay seller, and mine came with a Dustbag. And a Drawer Box. My Cles was a MC White Cles. So I do not know if Mono Cles' come with a Dustbag. I would think it should come with a dustbag. but I'm not sure!
Depends on the cles. From my experiences, any special edition (cherry blossom, cerises, groom), MC, or vernis ones have a dustcover. I have a mono cles that did not come with one but, my new damier azur did. I'm not sure about other lines.
