Thank you for viewing! ^o^ An essential item for clarinet maintenance! Leak Light This is a handmade item. It's been around for about 20 years. I've used it on my own clarinet from time to time. There are some minor scratches. This is a basic maintenance tool for woodwind instruments. You can easily check if the pads are sealing the holes properly by looking for light leaks. I think this is a helpful tool for clarinet players to have. The clarinet in the photos is not included. Thank you. (._.) P.S. I am also selling various musical instrument-related goods.
