The bottom of the tabs glued securely and can be readily detached again well - in terms of function, the child-designed bookmarks are top. Also, the price-performance ratio. After all, you get 18 reusable tabs with brightly colored designs. Not quite so much has given me, however, that the pressure of the tabs is quite grobpixelig and up close the individual dots of color are clearly visible. So it is not particularly fine print.
Does not change the fact that they work wonderfully and are super convenient. Therefore 4/5 points!
