Wizard Kraft product measurements are All approximate. All pieces are unique because they are hand crafted, flocked and painted to insure this, even between pieces from the same cast. When multiple pieces are ordered such as 12 x 2 inch River Straights with Temperate flock and Deep Blue water, these will all be different. We try to issue different casting shapes, but depending on the amount of the same size there may be duplicate overall shapes. But these will still have a different application of the surface material.
