I have never touched manipulation cards before, so I didnt have the slightest idea of what they were supposed to feel like, but when I received these cards I was shocked! They are super thin (about half a normal playing card or less) and they feel like paper. I like them having 4 pips but some cards came with only 2 pips (3 out of 52). Nonetheless, I will still keep practicing with these cards.

Do not drop them on the ground. After 1 week of continuous practice I could notice some dirt on them that prevents them from fanning.
