Pentel 0.5mm Size HB Shade Hardness Pencil Refill Replacement Spare Leads Hi Pollymer Super For Automatic & Mechanical Pencils (Pack Of 3 Tubes - 36 Pieces)

Reasonably priced and as a repeat purchase I know they fit and are of good quality.

Good quality, well packaged. Reasonable durability, better than most

Do just what they should, no issues

It's just normal lead but better. So it's kinda worth it, I'd definitely buy it again cause it's guaranteed to be good.

Good price, writes nicely and well travelled

Best quality. I’ve used a clutch pencil for half a century. I’ve always used a Pentel. There are cheaper refil alternatives but these always break for me or produce a poor line. You get what you pay for! Choose these.

Good product, good service

Excellent quality, very smooth.

They are the original pentel so they are good.
