Very good quality for anyone that is trying to advance in lettering or calligraphy. At times can be streaky but its not that serious. They are very very good and they have lasted a good amount of time. I would definitely recommend to anyone. They are worth it.
These pens are amazing, I have come across this brand while at work and many times I actually go to the store and buy some for myself. The life on these are amazing they last a good amount of time obviously depending on the use you give to it. I definitely recommend these all the time. Specially when someone is asking if they can keep MINES! haha! I always tell them where I got them and that I love them too.
Head over heels over ANY kind of SHARPIE! But in specific for these. I cannot begin with how much I love using them on a daily. For labeling, for calligraphy, for color coating things to be organized, even when taking notes at school, work or even a grocery list. Sharpie is great quality and the life on these are very good as well.
