I just did some cleaning yesterday, i notice the 1st Male Kerberos pleather starting to deteriorate, especially the boots & arm part, due to those parts being elastic, previously i've had Chuichi which is newer however started to deteriorate much earlier like 1.5 years ago, it seems no matter how high quality those pleather are & how much you take care of them they will still deteriorate in few years time.
Well guess i'm gonna try rubber dip them when the time finally arrives.
