These are Inaki Sebastian timpani mallets. I bought them quite a while ago and used them a lot, so the felt has come off quite a bit and is thin. I think they need to be re-wrapped, but I think they can still be used. The model number is unknown, but they are thought to be medium-hard to hard. The stains on the handles look like bamboo patterns? They were there from when I bought them. ⚠ Please read the profile before commenting or purchasing. #Inaki #Music #Sebastian #Mallets #Timpani #Percussion #WindBand #Orchestra
