It appears these container sizes match with one company's use of the terms. Of course, other sites do not necessarily ascribe to these terms.
Please, feel free to edit the entry to give it a neutral point of view. Mentions of gc.com are ok, but point out when the material is specific to gc.com. -- Scout
I just removed a link to a URL www.geocaching-containers.com that just redirects to another site www.shop4swag.com that is already on our list. - niraD 16:28, 8 July 2009 (EDT)
