I got it for the first time. It is really excellent. Its tip is very thin and precise. A bit long and narrow, it helps a lot in the use of correction fluid. The "weight" it has inside sounds quite big and that's why it blends the correction fluid mixture very well.
It covers very well, spreads easily on paper, doesn't peel off.
Because the quantity of the correction fluid is small, it doesn't have time to dry and create lumps.
I have already bought it twice, I prefer it. It's not one of the cheapest, but you don't throw it away half-finished, like some others.
