These are made with a 'gunmetal' colored PLA for the ferrules, black PLA for the mouthpiece tip, and the gradient wood PLA for the remainder. The tuning slide is stainless steel. Wood PLA is more expensive than regular PLA, so these whistles will run $60.00, whereas the standard non-wood whistles are $50.
(PLA is a bio-plastic usually made from corn starch or sugarcane. It's sustainable, non-petrolum based, and used in such things as medical devices and food service clamshell containers).
