A friend whose son will be starting school on a short notice, told me about 'Goed Gemerkt' (or 'Neatly Named' in English). They offer all kinds of labels for clothes, lunch boxes, sport gear etc. It is very easy to create your own label and select color, icon, letter type and of course text. A good idea for every one who is afraid of losing your child's belongings (and who is not?). Goed gemerkt ships around the world.
