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 it's completely waterproof, the firecrackers won't get wet even if they're submerged in water! This is a handmade bear deterrent made using rare, high-quality wood. This product is a tool for setting off firecrackers to avoid encounters with wild animals such as bears and wild boars during stream fishing, mountain climbing, wild vegetable gathering, bamboo shoot harvesting, 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 material used is mahogany. It is used in high-quality furniture, musical instruments, and other woodworking products. It is a material used for high-end furniture because of its high durability and beautiful appearance. It is highly water-resistant overall. The barrel is made of stainless steel, so it is rust-resistant. The cross-section was polished with a fine file using a lathe. It's smooth. The main body is coated with two-part urethane. It has a very strong gloss and is also highly 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 the adhesive. Details: Body Material: Honduras Mahogany Barrel: Diameter 16mm, Depth approximately 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 main body are listed in the tag. The overall length does not include the ring. As this is a handmade product, 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 very much.
