These are a bit thin, but it makes finding your holy book much quicker,  especially as your finger get less nimble with age. I had written my own written out on 3M sticky tabs, but after a while, they fall off. These are tape based, and so the tape goes on either side of a single page. There is a tab staggering guide so that the tabs are well aligned to make the book look neat and professional with the tabs being cascaded so all titles are able to be vued easily. I recommend these for anyone who likes to flip right to a page during Bible groups or during services.
