Thank you for viewing. Windsurfing boom Aaron V-Grip Monocoque Aluminum 180 x 230 26π The grip was scratched by a rescued cat that was kept in the workshop, so it has been replaced with a new shrink tube. The boom is a monocoque type, so it is durable. I used it for 7 to 8㎡ sails. The grip diameter is 26π, making it easy to grip even for people with small hands. For shipping, it will be delivered to the nearest Seino Transportation sales office (buyer pays). No returns or refunds. Shipping costs are expected to be high, so hand-delivery at Watarase Retarding Basin or Oyama Station is also acceptable.
