The Toyooka Craft pen cases have been mentioned a few times but not often or recently. I bought their 24 pen box with a drawer for ink 3 or 4 years ago at the SF Pen Show. I then bought the 4 drawer, 40 pen case. Today, my 100 pen box arrived, and I love it! I hate to think where this mathematical progression goes next, but meanwhile I am delighted with the design and workmanship of this case.
Each drawer has 20 slots and is deep enough for any pen I can imagine using. Size is roughly 18.66 x 8.27 x 8.35 inches. (W, D, H)
Enjoy!
