BICO"s unique approach to both design and manufacturing creates cutting edge jewelry for both men and women. Caring for your Bico Product: Chemicals used in traditional jewelry cleaning methods must not be used when cleaning your BICO product. Gently rinse your product in warm water and dry it with a soft cloth. Direct exposure to colognes and aftershave, pool products, and excess sweat can affect the coating and plating of your product. Furthermore, pendants and chains should be rinsed and dried if worn in the ocean.
