The Lucky Crystals name refers to the decorative motif with colorful stones. The source description says the design is inspired by a four-leaf clover, a symbol associated with luck and positive energy. It is a styling theme, not a promise of talisman-like effects.
Lucky Crystals comes with a universal mounting adapter. Place it between the phone and a properly fitting case, guide the loop through the lower opening and attach the strap. There is no separate mounting piece to search for.

When you are not using Lucky Crystals with your smartphone, you can also attach it to a handbag, wallet or keys and use it as a decorative charm.

Insert the smartphone and check that the adapter lies flat and the case still grips the device correctly.
Attach the strap to the protruding adapter loop. Before heading out, test the connection gently over a soft surface.
