The main difference between the Silk-épil 9 (225229) and the 9-006 (124.-) is the accessories and features included. The 225229 model includes 40 tweezers, is battery-powered, can be used in wet and dry mode, and comes with several accessories: cleaning brush, charging cable, mini shaver, shaving head and storage case. The 9-006 model, often offered at a lower price, may have a different or less complete configuration of accessories, which explains the price difference. Both models belong to the same Silk-épil 9 range, but the 225229 offers a version with more options and accessories for more versatile use.
