Key Points for Choosing Finished Products 1. Material Prioritize soft clay / stone plastic clay (not easy to crack, durable for long-term use). Choose resin / glass rhinestones; claw setting is firmer than adhesive setting. Use 304 stainless steel key rings and lobster clasps for accessories to prevent rust. 2. Style Couple styles are mostly two-piece matching hearts (pink & white / pink & purple), with glitter, gradient colors and small letter engraving. Girl styles usually feature full rhinestones, blush hearts and bow decorations.
