Kutsuwa Aluminum Pencil Cap - Color - Pack of 6

These are awesome. I can't believe that until earlier this year I never knew such an item even existed. Now that I have some, I can't imagine a pencil without one!! I can't vouch for the fit on every pencil but these work on my Staedtler Mars Lumograph, Tombow Mono 100, Mitsubishi Hi-Uni, and FC Castell 9000. I store my pencils standing vertically in the pockets of my Delfonics pouch. These caps are not only helpful in protecting the pencil itself (and their sharp points from my fingers) but also for a quick visual aid to sort graphite type--I separate H pencils (hard) from B pencils (soft). Very happy that Yoseka carries these since many local office/art supply shops do not.
