I know this is a hotly contested subject for artists. No review will please everyone, and as many people are die hard Prismacolor fans, and I have many Prismacolor pencils, a Prismacolor sharpener, the whole line of goodies. I love them, but in the last year, I have received one package of black Prismacolor pencils with a third of them broken in half, and my current pencils don't sharpen well and the lead is often broken inside the pencil, despite excellent care. This has not been the case until the last year of so. I tried these pencils as they were half the price (about the same as a 12 pack for a 24 pack). Theses are a bit harder, and so far none of them have arrived broken, and sharpen with all of my sharpeners well. Now as far as quality.
I first tried a pencil drawing of a horse and found the colors blended just as well as my Prismacolors. This surprised me. I only used a stub and Q tip. Thinking it was not a complete comparison, I made a series of squares for each pencil from each brand of pencil, and shaded them to compare the results. Again, nothing fancy like liquids to blend them, just a stub (new one for each type of pencil), and a Prismacolor blending tool for their pencils as well as the stub. While there was a small difference in the color they blended to (very small), the blending was at least as good for the Ohuhu pencils as the Prismacolors.
I recently purchased another set of Prismacolor pencils just to be sure they are not as durable as they used to be, and that my sets were damaged in shipping (I know the black ones that arrived broken in half were, but they were shipped in another order). If they are the quality they used to be, I will have to conclude my last sets were damaged in shipping. That will restore my confidence in the brand. So far, however, I wrestle with brand loyalty as I look for a way to prove the Prismacolor products better, when the Ohuhu work perfectly every time, at half the cost. I am no expert in pigment, but they sure seem similar. I am no professional artist, so I keep asking myself what I am missing, but then if they perform the same for me, does it really matter?
These are only my observations. You have to decide for yourself. I wonder if Prismacolor is using another process, or changed manufactures. If my new set works, I'll use both. If they are as bad as my last one, I'll send them back for the harder pencils. I am open to any constructive comments you may have - am I missing something?
