Pencils in 0.3 mm
Pentel Sharp P203 6th Generation-Pentel's present day flagship and defining example of quality.
rOtring 600-What many people consider the best pencil to buy in this era.
Pentel Sharp P203 4th Generation-The oldest pencil in my collection and, despite appearing the same as the 6th generation Pentel P203, there is one major difference between the two.
Alvin Draftmatic-Very similar to the rOtring 500 except for one thing.
Alvin Draft-Tec Retrac-A cheaper option for a retractable pencil.
Pentel Graphgear 1000-Most likely your best option in regards to features.
Zebra Delguard-A major game changer in lead protection back in 2016.
Zebra Delguard LX-An upgrade to an already good package.
Uni Kuru Toga Standard-Another game changer, except with lead rotation.
rOtring 500-The "not too hot, not too cold" rOtring out there.
rOtring 300-A rOtring for those with "lower" budget.
Zebra Color Flight-Very similar design to the Pentel P203, but how does it hold up functionwise?
Tombow Mono Graph Shaker-A shaker and clip mechanism?
Pentel Graph 1000 for Pro/CS Edition-As Clutch Situation says, the perfect upgrade to the Sharp.
Pentel Graphgear 500-The cheapest of the Graphgear Series by Pentel.
Pilot Airblanc-One of the cheapest 0.3 mm mechanical pencil available at the moment.
Pilot S5-An upgrade from the S3, but still has one main issue.
Uni Shift Pipe Lock-An interesting take on the retractable tip.
Pilot Fure Fure Corone-Same price as the Airblanc yet widely differing in regards to features.
