Alex and Ani bracelets are designed with adjustable features that allow them to fit a range of wrist sizes. Most of their bangles have a sliding mechanism that enables individuals to expand or contract the size for a comfortable fit. To adjust the size, one can simply hold the ends of the bracelet and gently pull them apart or push them together, which allows for easy resizing. It is important to be cautious while adjusting to avoid any potential damage to the bracelet or the charms attached to it. However, if the bracelet has a specific design that does not allow for adjustments, it is advisable to refer to the product details on the Alex and Ani website. There, you can find more information on the specific type of bracelet you have.
