Prismacolor Col-Erase: Can it be Erased?

During my pen-and-pencil retail therapy some days ago I picked a Prismacolor Col-Erase Carmin Red pencil. I'm informed by PencilTalk that Sanford which have been making these pencils along with Mirado and Mirado Black Warrior was due to close its US manufacturing facilities in 2009 and move to Mexico. This must have happened because the careful eye will discern the word Mexico inscribed on the pencil barrel.

Mexico inscribed on Prismacolor Col-Erase:



The Prismacolor Col-Erase boast that they are perfect for illustrating and animating, that they have a strong medium lead and erase with ease. And here I put the Carmin Red to the test. I made marks on

1. Winsor & Newton Cartridge Sketch Pad, 110gsm and on
2. Daler Cartridge Pad, 130gsm.

I used

1. Winsor & Newton Griffin eraser
2. Derwent eraser
3. the pencil's own eraser.

And now erased with its own eraser:




Shouldn't one expect complete erasure from a Col-Erase? Or am I asking for too much?
As I have mentioned before the pencil came with a bar code label stuck to it like there was no tomorrow. An anonymous reader has suggested erasing the sticky stuff off. It worked!

Prismacolor have got a wonderful website. Check out Col-Erase and all the rest of their products there and maybe leave your own sketch behind.
