I've noticed that in many (most?) of your mechanical pencil listings, you either say that the pencil has a fixed sleeve, or you don't say anything at all about the sleeve. This often leaves me wondering if the pencil has a fixed sleeve or a retractable sleeve.

It would be nice if you would mention on the product's page if the mechanical pencil has a retractable sleeve, because this is an important part of my decision to buy (I want to buy a MP with a retractable sleeve).
