Curious to know who else uses the Mally eye pencils? I do like it but because it's so soft I find it's a nightmare to sharpen. None of the cosmetic sharpeners I have will do the job and I have to get my son to use his scalpel-like modellers knife and even that doesn't do a brilliant job. Once it's sharpened a bit, the tip just collapses and crumbles to nothing after a single use. Any help would be appreciated My black pencil is now just a stump even though I've not actually been able to use it much on my eyes.
