Thank you for viewing! This work is a fully waterproof firecracker case, made as a single unit. It has no wasted volume and a cool design with high practicality. I came up with the idea because I felt it was a waste of time to take out firecrackers from a separate case when I was actually using it and wanted to get to the fishing spot quickly. Since the whole thing is waterproof, the firecrackers won't get wet even if they get submerged in water! This is a handmade bear deterrent made using rare precious 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, picking 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 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: Japanese Zelkova 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 main 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, 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.
