I think my answer got lost up above.

Make your own by using Rit clothing dye.

If this is considered bad practice, then I apologize, but you might as well all know, before someone starts doing it, and you wonder how.

That makes me repeat the questions.

Do people collect strikes or the plastic that they come in?

Is this going to get like Beanies where the paper tag condition once made a difference.

Are strikes going to be graded by the condition of the plastic case or the color?
