Review: I love Staedtler but I wasn't expecting much for the price ... - I'm not sure what type of pens the negative comments received. I love Staedtler but I wasn't expecting much for the price of the pens. However, I am pleasantly surprised. Amazing colours barring the red isn't as bright as I'd have liked but all the other colours are amazingly bright. The pens are made from cheap plastic but what do you expect for the price? Great pens and very easy to write with. Definitely will be buying again when I have wore these ones out.

### ⭐⭐⭐⭐⭐ Great pens

Love these pens, bought them for work and each one works great. When you buy different coloured pens in a set there is always one that doesn't work but had no issues with these! Great range of colours and nice and smooth to write with.

### ⭐⭐⭐⭐ Nice pens :)
*by P***L on 25 July 2020*

They are nice pens. The colour isn’t vibrant a lot. I love stationery so I have a lot of pens from this company. I think those ones have the lowest quality even in the plastic that they’re made off. However good value for money.
