What is the Zebra M-301?
It is Zebra’s stainless steel mechanical pencil: a short, light pencil with a metal barrel and clip, made to last longer than an all-plastic school pencil. Zebra Pen calls it the original stainless steel mechanical pencil and “America’s number one steel mechanical pencil.”
It is the pencil partner of the Zebra F-301 ballpoint in Zebra’s Steel 3-Series, and shares its look. On Amazon US the 0.5 mm 2-pack had 6,989 ratings and ranked #71 in Mechanical Pencils on October 22, 2026.
Zebra M-301 specs
| Spec | Zebra M-301 |
|---|---|
| Lead sizes | 0.5 mm, 0.7 mm |
| Length | 13.3 cm (5.2 in) (JetPens) |
| Diameter | 8.6 mm (JetPens) |
| Weight | 9 g with lead (JetPens) |
| Sleeve | 3 mm, fixed (JetPens) |
| Barrel | Stainless steel; plastic grip (JetPens) |
| Eraser | Under the plunger cap, refillable (Zebra) |
| US packs | 54012: 2 black 0.5 mm; 54010: 12 × 0.5 mm; 54310: 12 × 0.7 mm |
JetPens lists the same length, weight, diameter and sleeve for the 0.5 and 0.7 mm models.
Why is the M-301 so popular?
It is cheap, light and tough, with a metal barrel that survives backpacks and desk drawers. Zebra highlights three things: the stainless steel barrel, the metal clip that keeps it in place, and the shorter length that fits shirt pockets.
At 9 g it weighs about as much as a plastic pencil, so the steel adds durability rather than weight. The textured grip is plastic, and the eraser hides under a metal cap at the top, like on a classic drafting pencil.
Which M-301 should you buy, 0.5 or 0.7 mm?
0.5 mm for small, neat handwriting and math; 0.7 mm if you press hard or want a darker, smoother line. Thicker lead breaks less often, which matters on a pencil without a lead cushion.
Zebra Pen’s own store sells the 0.5 mm as a 2-pack and both sizes in 12-packs, all with black grips; Amazon and office stores carry the same packs. Buying a 12-pack brings the price per pencil down further, which is why classrooms and offices stock it.
How do you refill the M-301?
Pull off the plunger cap, take out the eraser, and drop standard lead into the tube. Zebra says it refills with standard lead, so any 0.5 or 0.7 mm lead of the right size works.
The eraser is replaceable too: JetPens sells Zebra eraser refills for the M-701, M-301 and M-402.
How does the M-301 compare with other everyday pencils?
It’s the metal-barreled budget pick; the P205 is the drafting classic, the Xtra Smooth the disposable bulk buy.
| Zebra M-301 | Pentel Sharp P205 | BIC Xtra Smooth | Zebra DelGuard | |
|---|---|---|---|---|
| Barrel | Stainless steel | Plastic | Plastic | Plastic |
| Sleeve | 3 mm fixed | 4 mm fixed | — | Spring-loaded guard |
| Length | 133 mm | 145 mm | No published length | 137.3 mm |
| Eraser | Under the cap | Under the cap | Top cap, clicks to feed lead | Refill: Zebra G |
Figures for the other pencils come from their guides. Choose the M-301 for a durable everyday pencil that fits a pocket; choose the DelGuard if you keep breaking lead.
Who should buy the Zebra M-301?
Students, office workers and anyone who loses or breaks plastic pencils. It is also a common first “nice” pencil, because the steel barrel feels sturdier than its price suggests.
People who want a long, balanced drafting pencil may find it short, and heavy-handed writers using 0.5 mm should consider a lead-protecting pencil instead.
Where is the Zebra M-301 made?
Zebra doesn’t state it on its US product page, and the Amazon US listing we read doesn’t either. Zebra Pen Corporation sells it in the US; its parent, Zebra Co., Ltd., is based in Tokyo. Check the package.
Frequently asked questions
Does the Zebra M-301 have an eraser?
Yes, under the plunger cap. Zebra says it is refillable, and JetPens sells Zebra eraser refills that fit the M-301, M-701 and M-402.
What lead does the M-301 take?
Standard 0.5 mm or 0.7 mm lead, depending on the model. Zebra says it refills with standard lead, and the US pack is labeled HB lead.
Is the M-301 good for drafting?
It has a 3 mm fixed sleeve that works with a ruler, but no lead-grade indicator or weighted grip. For serious drafting, a 4 mm sleeve pencil like the Pentel P205 is the usual pick.
Is the M-301 the pencil version of the F-301 pen?
Yes. Both belong to Zebra's Steel 3-Series, with the same stainless steel barrel, black grip and clip. The F-301 is a ballpoint.
Can the M-301 sleeve poke through a pocket?
The 3 mm sleeve is fixed, so it doesn't retract. Retract the lead and clip it point-down at your own risk; a retracting pencil is safer in a shirt pocket.
Is the Zebra M-301 made in the USA?
Zebra doesn't say on its US product page. Zebra Pen Corporation sells it in the US; the parent company, Zebra Co., Ltd., is in Tokyo.
