These are tubed for 3/8ths and 2 inches. The tube for the Majestic Squire Kit.
They were cast in epoxy resin. The top and bottoms are dyed wood, the middle is abalone shell pieces that were carefully glued directly to the tube and cast.
Please use a squaring jig with a sander to square up your label cast blanks, a barrel trimmer is not recommended, as it can damage the label.
