I'm selling these clubs because the latest Modus 110 didn't suit me, so I'm replacing them. These are a manufacturer's custom version. Also, the 7-PW irons come with a warranty and specifications sheet. The manufacturer's custom specifications are as follows: 9 iron: Loft 40 degrees (41→40, 1 degree stronger) PW: Loft 45 degrees (46→45, 1 degree stronger) Others are standard.
