There are 20 fine tip markers. The colors are vibrant and bold. My 10 year old son tested these out. He drew on a white t shirt. For the most part the markers didn’t bleed through but where he put more pressure and tried to make it darker it did bleed through some. He also said that when he would draw on the shirt it would pick up the small particles from the shirt and stick on the marker. This is a nice set of markers for a child but I don’t think I would rely on these for a “professional” job. The packaging is just a simple plastic case. There are two stickers to hold it shut but once it is opened they are no longer sticky and it comes open with no effort.
