Comments about Uni-ball Uni� Paint Oil-Based Paint Markers; Bullet Point, Black:
I didn't use the pen very much, but it was out of ink in about 2 weeks. Also, there is a notice on the pen that the state of CA found that some chemicals in the pen cause cancer, and there is another notice to use in well ventilated areas. So - this made me a little uneasy about using this, I've not seen a cancer notice on a pen before. I will not purchase again because of this notice and because it ran out so quickly, besides this, it really worked well for blacking out sensitive information without possibility of seeing through the ink.
Bottom Line No, I would not recommend this to a friend
