I've been looking for something for labeling of t-shirts and came across this. It's really very easy to use - choose color, take appropriate pin in the hand and get started with the desired subject. The material must be already properly hold and have washed once before, but it went very well. Also, the fixed iron was without problems and with me the colors have not thereby diminished. It is first of all washed and has the T-shirt and the font super survived. Since it is not liquid, it can be very well used for children and if you paint itself a problem - without iron over it all goes out again. On the next children's party it will be used!
