I haven't had them long enough to know how well they will hold up, but they came nicely packaged and seem to be made of good quality, especially for the price. If I discover a major flaw with them, I will come back and talk about it.

So far using 1. It is amazing , great coverage and works great compared to other brands I have bought previously

Good bright colors, they all worked, and even months later they still good.

Effective on plastic. Will see how long it lasts

Does what they are supposed to

nice easy flow from brightly colored markers. I hope they don’t try up too fast..

Fantastic Paint markers

These are great for marking engine parts. I used them on a few spare parts for my Mazda rotary engine. Things like oil control ring springs come from the factory with paint marks to indicate their proper location, but when you're rebuilding with used parts, this is kind of nice to mark them again after cleaning and inspection so when its time to stack the engine you're ready to go. Or for those spares that sit in the toolbox like rotary engine oil pressure regulators of varying origins.
