I found what for me what is an ideal storage cabinet for all my pen making supplies. It's a bit old fashioned and an outdated piece of office furniture. An 8-drawer file cabinet. Not those huge ones for paperwork. This was originally made for filing two horizontal rows of 3 x 5" file cards per drawer. Actual space inside drawer is 4" usable depth, with a center divider 2" tall, interior space is 6 1/8" W x 27 1/2" D for each half of an individual drawer. Up to 6" pen blanks fit nicely . Actual external dimensions of the cabinet are 28 1/2" D x 15" W x 52" H. Pen hardware kits whether singles or bulk packs fit nicely. This keeps my pen making supplies reasonably well organized, with plenty of storage space for spare drill bits, tubes, disassembly pliers, with lots of space left over for other small tools and supplies. This particular cabinet was made by Steelcase, color is silver, not that it matters. FWW each drawer latches closed, beautiful ball bearing drawer suspension, like high quality tool chests. Most larger cities have a business or two that deals with used office furniture. Another great possibility would be an old 24 or 27 drawer cabinet. The drawers are about 9" x 12" in size and about 3-4" deep, perhaps about 30" W and 36" H. These also can be found at used office furniture stores.
