Even though it is pretty expensive, I wouldn't allow that to stop you from purchasing. I can hand on heart say that since buying this tasbeeh, there are not many days that go by where I will not be in a state of constant dhikr. May Allah swt bless you immensely and allow this to be a source of sadaqah e jariyah for you. I do dua for you regularly for this constant reminder to do dhikr e.g. at job interviews, walks, waiting in lines place I usually wouldn't have remembered to do dhikr This charm reminded me. I would, however, use a stronger thread as the constant use did end up deteriorating the threat, I have full faith you will sort this out. May allah swt place lots of barakah in your business. ameen sum ameen
