Inspired by the AT on: The Labelless Home post last week, AT reader g tipped us off to Specialty Bottle. It's an online national supplier of containers for anyone wanting to go labelless.
They have small stainless steel tins (in some sizes we've not been able to find anywhere. They also carry plastic, glass, and stainless bottles with flat screw-on lids, pumps, or spritzers. We think you could find containers for storing almost anything for the kitchen and bathroom here. (thanks for the tip, g!)
