Plastic is fantastic, but not indestructible. Please keep in mind that La Manso rings are jewels, and they need to be cared for as such. Contact with liquids may affect their durability, even salty water, or your own sweat for prolonged exposure. Take them off when cleaning your hands and avoid any solutions, specially hydroalcoholic gel, as they might wear away their shine or weaken the structure.
You can use a small brush to keep La Manso engraving looking perfect.
