Great quality for the price.
Pens look great. The highlighters don't work very well, they seem like they are dried out.
Very good qualitiy. This item turned out looking just like the picture.
It was a nice concept however, it was a lot cheaper looking and flimsy to use.
It is a nice calculator that seems to take a lot of wear and tear.
I am not a fan of the material used, polypropylene. It doesn't seem to be durable at all.
