We have had these Coconut shy posts manufactured from galvanized steel to our own design. The poles are 1m high, with a small ring at top of posts so that normal sized coconuts should be easy to knock off. They are galvanized so will not rust for many years and the coconut ring lies slighly below top of post so that the pole can be easily hammered into the ground without the ring interfering. Made in Britain. Coconuts not included (but are easily purchased at a grocery store).Approx. dimensions: 3.3 feet long. Inside diameter 3.1 inch.Made in BritainProduct Ref.: 0021R2
