Koh-I-Noor 2mm pencil and lead, 6 color set

I wanted to try out some colored pencils for daily business. Mostly to make marks or annotations on documents in a more visible way compared to a regular black pencil. In the past I did not have a very good experience with mechanical pencil colored leads so I tried something else, 2 mm leads. I found the only 2 mm leads in color available locally are the Koh I Noor ones.

They came in a 6 pack that contains a black one, red, blue, brown, yellow and green. The cool thing about them is that Koh-I-Noor also sells a similar pack with 2 mm clutch pencils. The pencils come in the same colors as the leads. Pretty nice.

The leads are made in the Czech Republic and come in a red plastic box with a clear top that has a Koh I Noor logo. The top slides to reveal the leads inside. They are very secure inside but if you only have one clutch pencil and you want to switch leads often grabbing them from the pack is not too easy.
The price is good as with all the Koh I Noor products. I got them for 1.51 EURO or 1.84 USD.

The colors are ok, not very vibrant but not dull. The black is the one I do not like. It feels like a colored pencil instead of a regular lead, plus it could be a bit darker. For example, a Faber Castell 2 mm lead 3B is smoother and produces a darker line.

The brown, blue, green look good and can be used for marking stuff with no problems. The red is a bit dull and not very vibrant but it is ok. The yellow is no surprise here, it can only be used for highlighting, as it is too washed out to write with it.
My favorite colors are the green and blue, followed by the brown and then red.
An erase test showed that they are not too stubborn and can be erased without too many problems. I have put to the test the Rotring Tikky and the Faber Castell Dust Free 187121 erasers. The Faber Castell did a much better job.

A Parker Jotter in the movie Oldboy

 In the intense thriller Oldboy (2003) the main character is imprisoned along with a stack of envelopes, papers, and a Parker Jotter pen.

A great instrument for writing, very classy and slick

But apparently, you can also use it as a makeshift tattoo gun. Take the refill out, heat it and ink away. I not going to comment about this...
