Polishes excellently, faster and cleaner than sapphire ceramic and sand filing. Feels more like loops than as files / rasps at (gaanz rough estimate: 800'er / 1500'er grit). The smaller one is a finer, specially good for a smooth finish of the nail edges. Can be cleaned supergut. Looks quite appealing / quality of. Unfortunately is quite thick (2-3mm?), Must be true because otherwise glass breaks.
Speaking of breaks, lubbers and all case Lasser should keep a distance or put carpet in the bathroom. But please do not Pull star because the glass file is broken when she kisses stone floor. Or buy deodorant, perfume and champagne glasses even if they are made of solid rubber?
