I recently found out that glues in the world are made from collagen in animal hides, bones, and fish. Since glue is in almost every product that we use, it would be hard to find out the sources that the glues used. Is it najis to wear shoes, book bags, phone cases, phone screen protectors, and wallets, etc made with glue with glues that used animal parts? Also, is it considered istihala?
