this be my fave ring of all time . it come with a string around it so it will not fall a part when you take it out of the box . although , mine have to be `` take '' apart . it do not just fall apart like some of the looser knot do . I love this ring & the company have a video you can watch & learn to how to put it , & other puzzle ring , back together . the indviual band be thin & can bend so you have to be nice it , but it be well worth the money .
