-: Contrabass Bow - Case: grazioso - Material: Carbon - Rosin (used): Samuel Kolstein Ultra Bass Rosin This is a contrabass French bow. The frog's engraving is faint, making it difficult to determine, but it's likely a grazioso bow. I've been using a German type bow, and considering a switch to the French type, I was looking for a durable carbon bow. I purchased this used about six months ago, but after using it a few times, I found it difficult to transition to French style, so I'm selling it. I believe it's in relatively good condition, please judge from the photos. The price includes the case. If you'd like, I can also include the used rosin. No returns, so please ask any questions in the comments section before purchasing.
