PentelAin Stein Mechanical Pencil Lead | Tip Size 0.5 Mm | Lead Of Grade 4B | Pack Of 40 Pcs X 2 Set (C275-4B), Ink black

I am happy with this product. Very helpful for an artist to attain darker shades with these. They are of 4b grade amd as dark as 8b. We can use them in any 0.5mm mechanical pencil.But these are quite costly to buy.But it is okay because I think they are cheaper than graphite pencils and enough dark.

This is a value for money product. It doesn't break easily, although it is 4B.

They are very pricey for pencil leads . But quality is awesome . They write dark and smooth, but break easily given the softness of 4b

One of the best products sold at inflated price by the seller.

Nice product.
