Well I am surfer from the 60s and at the present time I am shaping tiny small surfboards on foam and fiberglassed as usual. Sizes are 3.75 inches long for the Key Holders or Neck Hangers ; 6 inches long ones for those you hang them in the rear view mirror of your car, and 8 inches long ones for the ones taht could be used as Trophies or gifts. Let me know if you or someone that you know may be interested to buy from me. Prices: from US$ 5 to US$ 15. Plus Shipping and Handling . I am living in PERU , South America.
