I purchased this when my child was in junior high school because it was required by the school. My child is now in high school, so I bought it about five years ago from the school, and I don't know the brand. There is a name written on the back, so I would appreciate it if you could cover it with a sticker or something. This is a set of four carving knives: a 6mm round knife, a 3mm flat knife, a 6mm flat knife, and a 6mm skew knife. Outer box: 23 cm x 8 cm Thank you.
