I don’t know about anyone else, but I certainly have memories of being fascinated by double-ended colored pencils. I actually might still have my first one around somewhere because, even though I ended up with a couple different ones in my pencil pile™, there just wasn’t much use I could find specifically for a double-ended colored pencil. But the box for the one I’m looking at today, the Vivifan Bicolor, has (as best I can make out since I don’t read Spanish fluently) listed uses for each side of the blue and red pencil. The blue side is for “writing” and the red side is for “correcting” (escribir y corregir respectivamente), but is that really a good use scenario?
Like a few other Peruvian writing implements I’ve reviewed recently, the Bicolor has a rounded, triangular body that helps with grip and prevents it from easily rolling off the table. It’s painted red and blue on the sides corresponding with the color of the lead, coming together in the middle at a surprisingly straight line (I don’t know if that line exactly corresponds to the leads, though). Near the center, stamped in gold letters, are “Vivifan” and “Bicolor” which is enough, but I would’ve liked some more information.
In the package, the points are very cheaply made with 3 flat cuts, but they are usable (though the points were broken or blunted on some of mine during the trip from Peru to the USA). The writing has a more-or-less standard, waxy colored pencil feeling. Coverage is pretty good when bearing down (the blue covers slightly less completely than the red), and at normal writing pressure they are darker than the average colored pencil. But, in my experience, they become unsightly and uncomfortable after only a few words. The fire-engine red and navy blue colors are unspectacular and almost non-differentiate-able from Crayola orange-red and blue pencils, but they get the job done. Both the waxy-ness and the not-good-for-art colors provided help lead to the very standard problem with inexpensive colored pencils of them not blending very well, but the packages says they’re for writing so that’s less of a concern.
I’m still not really sure what I would use this for. The red side is good for marking corrections to be made, but the blue side is not good for writing. The color set is too limited for most artistic applications and the difficulty there is compounded by the inexpensive waxy-ness. Still, if you’re looking for a space-saving or easier-to-keep-track-of way to have both a blue and red colored pencil with you, this would be a perfectly adequate (and comfortably designed) way to do that.
