Good quality keycaps, feel thick and won't absorb oil. But the fact that you have looked at PBT caps already means that you have an idea about this product. I am happy with the product but I would advise anyone reading it to choose a color wisely. I think white looks better in product photos, but I have trouble making out the keys when I have to look at the keyboard during the day. I think black would be the best choice in this regard. Nevertheless, the thing is of high quality, pleasant to the touch and caused me no problems. I put white caps on the Keychron K8 and personally think it looks a bit feminine now, but it's up to me.
