Отзыв о 16-пак скрытых петель для кабинета - скрытая наружная поверхностная установка 90 градусов для дверей кабинета от Sean Flint

I tried to bend the hinges to see how it worked and could not get them ( zip tried several) and a friend tried and could not get any of them to budge. Also, no instructions on how to use them. I know I can look online, but I shouldn't have to find it. I'm going to ask a couple more people in case I'm doing something wrong. I waited awhile to get these and searched online to get exactly what I wanted. I guess if I cant get them to move I guess I'll have to return them and get something else. Hinges like these by another manufacturer are also online and cheaper, but these had good reviews. What a shame I really wanted them to finish my project by the new year . I guess next year lol.
