Thanks for your review and feedback! It sounds like you have the Protective Obsidian and Tibetan Pendant Mala, which can be adjusted. There is a knot on the end of the mala that acts like a tube that can open and close. Your mala sounds like it was pulled a bit too tight, and slightly opening the piece will alleviate that pulling.
I hope this information is helpful! We appreciate your review, and for supporting Nepalese artisans! Please let us know if you have any other questions or need help adjusting your mala. We're always happy to assist!
