Pentel Arts Tradio Stylo Sketch Pen Refills, Black, Box of 12 (MLJ20-A)

The ink and ease of drawing with the pen holder allows for easy sketching

Personally, I love this pen. Despite the expensive shell, it's a cheap, but very good pen to sketch with.I also have a rOtring pen sketch pen as well, and as satisfied as I am with it it lacks character. To an extent, each nib is different. I've had some that would flick than others, some more flat no matter the angle. The quality is consistent, but there's enough differences between them that bring a new perspective to me.Each refill I've used has never been dry, at least in my experience, and I still have a few refills left from my last pack from over 3 years ago.

In life, a good product is that which you are not afraid to wear down. These pens release lots of ink and therefore write boldly. Tips are a firm, felted quality which can deform if you press too hard. These pens use up quickly so the longevity of the tips is not an issue. Ink is of the highest quality and does not bleed through the page.

Good deal on my favorite pens. Very economical and very good pens.

The Tradio Stylo pen has become my favorite everyday pen of choice -- and I carry one with me all the time (in my purse, in my pocket, wherever I can find it fast and keep it safe). Buying the refills by the box was definitely the wise choice, as it brought the price down considerably and made sure I would never have a dry pen. If you are proud of your penmanship (the Catholic nuns taught me well) -- this pen is a great way to show it off.

They write like a dream and last a pretty long time.

An economical way to always have refills for my favorite pen! I use these pens at home and at work, I love the way they write. The Pentel Tradio Pulaman "fountain" pen and the Tradio Stylo sketch are basically the same pen, and these refills fit either pen. Considering single refills are about $4, this pack of 12 is half the price per refil.

Purchased this box to refill my MLJ20 pen and these are junk, finally needed to crack it open and one was DOA won't write, the next is just not exactly great. As an artist I need tools that are reliable and these are not.
