WestChinagraph Marking Pencils - Black (Box of 12)

If you can sharpen one of these without the lead breaking then you are a better person than me or my engineer neighbour. After sharpening 3 of them down to 2/3 of size, with each of them breaking at each time of sharpening, before use, I can only assume they were repeatedly thrown against a wall or dropped from height to assure they were useless. Instead of buying these, give the money to charity, becuse you will have just as many functioning pencils if you don't buy them!

I bought these because they were quite cheap through the Amazon addon program. I wish I hadn't bothered, or at least read the reviews beforehand. You do have to be very, very careful sharpening these. And they don't write on anything that's even vaguely cold, wet, or curved. Also, if you try to write over a mark again, it erases the previous mark. Try writing an uppercase "H" without writing over the previous mark.All in all, I can chuck these in the bin.

These are probably the worst chinagraph pencils I've experienced - and I've used hundreds over the years. No matter how little they are sharpened the "lead" drops out before or during first use. Three days of attempted use and the entire box of ten is almost gone. On the rare occasions it is possible to use them they do not mark on the laminated surface of the charts - which rather defeats the point. Ho hum, off to the stationer to buy my usual brand.

Never used chinagraph pencils so maybe its normal for them to break so much? Cant really say but these are hard to use because they break all the time. I don't sharpen them to a point as that makes them snap off too. They do write on glass etc tho.

These are excellentI use them if I get a mark on my cars dashboard or interiors, just draw on and smudge in and the marks disappear great product
