Smooth and veined Double Header designs
Compare the shared length and the surface detail for the two Classic options.
Match the exact variant
The smooth and veined Classic listings both give 18 inches overall. The meaningful published difference is the shaft surface. Confirm the color and full product name on the linked listing.
Look at the side of the product
A side view can show where raised details start and how far they extend. Use a labeled measurement for width. A photograph alone gives no reliable scale.
