Thank you for viewing. If my memory serves me correctly, I purchased these dart barrels about 10 years ago from an online shop for around 5,000 to 6,000 yen. I've looked into them, but I couldn't find the manufacturer or product name, so I couldn't find any detailed information. They might be a no-brand product. The material is probably 80% tungsten. They are a torpedo shape with a silhouette close to a straight barrel due to a very gentle taper. They have a simple design with only 10 ring cuts on the grip area, making them easy to handle. I think they are easy to use for beginners to advanced players. I used them for about 3 months. There are no noticeable scratches, and the cuts are still in good condition, but they have become quite dull due to aging. Please take a close look at the images and only purchase if you understand that they are used items. Specifications Material: 80% Tungsten? Single barrel weight: 16g Length: 41.0mm Max diameter: 7.0mm Type: 2BA (Measured by the seller, see images) Price negotiable. Feel free to comment. The items are only 3 barrels. They will be placed in a zip-lock storage pack. This item will be shipped promptly via Yu-Packet Post Mini. #darts #barrel
