This listing is for a Tibetan rosewood wrist mala with dzi beads spacer. Each rosewood bead measures 8mm size approximately. There are 21 beads altogether excluding the Guru bead. I strung this mala and it is made adjustable to fit any wrist size. Malas are usually used for meditation, saying mantras, prostrations and so on. Wrist malas are specially used for prostration to count. When you do prostration, you wear on your palm under your thumb and do prostration. While the mala is not in use you wear on your left wrist. You can usually see people with malas in Tibet, Nepal and India specially around those stupas or monasteries.
