The tabs are small repositionable label whose "upper portion" is designed with child-friendly animal motifs. This upper part does not stick, it is intended in the book look out above. Through the removable glueing area you can use the tabs several times. My son takes as Einmerkhilfe for exercise books and books. One pack contains 3 sheets with 6 different motifs, ie a total of 18 tabs. Nice idea - the value for money is ok.
