Thank you for viewing! This work is a fully waterproof firecracker case, made as a single unit. It has no wasted space and a practical, cool design. I came up with the idea because I personally felt that "it's a waste of time to take out firecrackers from a separate case when I want to get to the fishing spot quickly." Since the whole thing is waterproof, the firecrackers won't get wet even if they're submerged in water! The material used is Claro Walnut. It has very strong figure. It's a very expensive, high-grade wood. This product is a tool for setting off firecrackers to avoid encounters with wild animals such as bears and wild boars when fishing in mountain streams, hiking, gathering wild plants, harvesting bamboo shoots, camping, etc. You can use the firecrackers one by one, accurately in the direction you want to set them off. Detailed usage instructions are often found on video-sharing sites. The whole thing is very water-resistant. The barrel is made of stainless steel, so it's rust-resistant. The cross-section was polished with fine sandpaper using a lathe. It's smooth. The main body is painted with two-part urethane. It has a very strong gloss and is also very water-resistant. Since two-part urethane is used, you can wipe it clean with chemicals such as alcohol if it gets dirty. Epoxy is used for bonding. Details: Body Material: Claro Walnut (Exquisite Figure) Barrel: Diameter 16mm, Depth approx. 67mm, all stainless steel pipe Adhesive: Epoxy Firecracker Case: Aluminum (Fully Waterproof) Ring Part: Iron Coating: Two-part urethane coat The diameter and overall length of the body are listed in the tag. The overall length does not include the ring. This is a handmade item, so there may be minor scratches, measurement errors, slight deviations in the center of the case, and minor unevenness on the painted surface. Please understand this in advance. Firecrackers are not included, so please prepare your own. Please use at your own risk. If you have any questions, please feel free to contact me in the comments section. Thank you.
