Perch leather has a large scale pattern and is the thickest of the fish leathers. The texture can be rough with the open scale pattern. If the scales are smoothed down - a different finish will appear but the leather is still strong. Looks good in light and dark colors and when combined with metallic finish it is unique. Size range = small (0.66 to 0.74 sq ft), medium (0.80 to 0.87 sq ft), large (0.94 to 1.05 sq ft) and x-large (1.19 to 1.36). Average thickness = 0.8 mm (click on photo to zoom in for scale pattern).
