I use Combi too, my sister went to department store to look for combi 洗奶樽液, but the sales gave her a BIXX 洗奶樽液,cos my sister dun know these kind of product very well,so she paid it and take it home, after she uses it she found the product is very bad and ask me why combi's product is so bad........she finally find out that's not Combi and so angry about the sales and the BIXX product... so plz be careful~~ cos the packing of the BIXX product is very simular to Combi's one.
