Thank you for viewing! This product is a fully waterproof, integrated firecracker case. It has no wasted space and a practical, cool design. I came up with the idea because I personally felt it was a waste of time to take firecrackers out of a separate case when I wanted 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! 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 is rust-resistant. The cross-section was polished with a fine file using a lathe. It's smooth. The material used is African Padauk. It is characterized by its beautiful red color and is used in high-quality furniture, musical instruments, and other woodworking products. It is a material used for high-quality furniture because of its durability and beautiful appearance. The main body is painted with two-part urethane. It has a very strong gloss and is also very water-resistant. If it gets dirty, you can wipe it off with chemicals such as alcohol. Epoxy is used for bonding. Details: Body material: African Padauk 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 body are listed on the tag. The overall length does not include the ring. As this is a handmade product, there may be minor scratches, measurement errors, deviations in the center of the case, and slight 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 us in the comments section. Thank you.
