Ideal for those labels are, for example in project work with children, adolescents or students who do not yet know each other and come together only in the context of a specific action. It facilitates mutual response (and also getting to know) if you quickly record the name and visible affixing of the outerwear. Previously I have always taken for masking tape. This naturally also applies, however, does not look as appealing. In addition, at the same time can still print a small colored logo on the labels. That looks a bit more professional and also comes in handy when multiple groups are to be distinguished.
I have the labels provided in advance with a logo, then noted with a black permanent marker, the name of the project participants. Both worked really well. The surface has through her silky shine a bit nobler than simple labels. The adhesion to the clothing is perfectly adequate.
