I was very curious about the Pilot Color Eno Mechanical Pencils ($2.75 each) so I bought all eight colors. The are 0.7mm colored pencils in mechanical pencil form and they are supposed to be erasable in the same vein as the Col-Erase but in mechanical pencils which means that pencil sharpeners would not be needed. So, I thought these would be worth a try. Each pencil is $2.75 each and there are replacement colored leads ($1.65 per tube) in the original formula and newer Neox leads ($3.30 per tube) as well and there are replaceable erasers too. ($1.65 per pack of 5)
Because the leads are 0.7mm, you can get a fine line but there are some sacrifices. If you press too hard on the fine 0.7mm lead, it will snap. But with some of the lighter colors like the yellow, you can’t really see the color unless you bear down on it. Some of the other colors, like the blue, is just too hard and scratchy. You can’t get a rich, creamy color like you can with other colored pencils because the lead had to be formulated such to hold together in such a fine diameter. So, yeah… sacrifices.
Based on my experiments, I wouldn’t recommend getting ALL the colors. I’d recommend getting the “animator’s friends” which would be the soft blue (AKA non-photo or non-repro blue) and red (which is similar to the beloved Col-Erase Vermillion or Carmine Red favored by animators). I would recommend, if you like thes ecolors, to then upgrade to the Neox leads though.
I also like the violet and pink pencils for sketching. The violet is actually quite dark and smooth and, conversely, the pink is pretty light. I liked the pink so much, I actually upgraded the lead to the Neox which doesn’t seem to wear down quite as fast. I burned through three of the standard pink leads in about a week.
Above are some quick sketches using the Pink Neox and the standard soft blue leads.
The colors I wouldn’t recommend are the yellow and the blue. The yellow was just too light to be useful and the blue was the hardest lead of the lot. Maybe I got a dud lead but it was super scratchy and uncooperative. I just couldn’t get it to lay down any color. I might try the Neox lead for the blue pencil to see if I have better luck because the stock lead did not do me any favors. I found the orange and green to be acceptable but not colors I’d race out to buy again.
As for the erasability, I’d not recommend the erasers anymore than I do the erasers on Col-Erase. They do erase a bit but its by no means a complete success. They are just OK. I would recommend trying other erasers like a foam or plastic eraser for better success. The nice thing is that the pencils are not super smudgey like graphite and that their erasable tendencies mean that if you use these as part of a base drawing for a painting or inked artwork, you can choose a color that might coordinate with your overall color palette so that it will blend in and disappear as color is added where graphite might gray your colors.
For sketching in meetings, the Pilot Color ENO mechanical pencils are a lot less intrusive to use rather than being the d-bag who brings in the handheld sharpener and leaves a pile of shavings on the table. They also make it easier to have a good portable kit for travel as the pipe for the lead is fully retractable into the plastic barrel so it will not be damaged in transport.
Note: These pencils were tested on the Block Bitacora spiral-top 90gsm bond paper made by Minerva from Peru. Acquired in one of the many kits received from Rad + Hungry.
