Like many instrument cases, clarinet cases don’t last as long as the actual clarinet, so bin the old one and purchase a new one to give your clarinet the protection it deserves. We have a small selection in stock and the Champion ones…there are two models, are good value. The zips, or zippers as some people call them, look pretty durable, and to date we are not aware of any problems with them. Other makes we have in stock are the BAM Trekking and two models by Bags, who are a Spanish company. These are good quality and should last longer than a cheaper one.
