These pens are amazing! Don't get me wrong I will probably buy them again but the one problem is they dry super quickly. I know there is still ink in the pens but the ballpoint won't write. I have tried a million times to get them to work again but after weeks of useless attempts I finally gave up and threw the pens away. I still really like how they write and I've noticed the colored ones tend to dry out more quickly compared to the red and black. They are super thin and always turn out pretty but I will be sticking to my basic colors next time.
