The reed case pictured is made from Red Mahogany wood and shows the no holder option. It is beautifully finished with a Golden Pecan stain and high-gloss polyurethane for a waterproof and scratch resistant exterior. You may also choose the traditional ribbon style slots used for holding individual reeds. For the ribbon style, the plexiglass is affixed to the bottom directly above the slot holding the clarinet and saxophone reeds. For the no holder option, the plexiglass covers the whole bottom portion of the case. The plexiglass keeps the reeds from warping. When the case is closed, the reeds are pushed down by the soft felt on the top side of the case.
