Thank you for viewing! This work is a fully waterproof firecracker case made in one piece. It has no wasted volume and a practical, cool design. I came up with the idea because I was using it myself and felt that "it's a waste of time to take out firecrackers from another 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 get 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 stream fishing, mountain climbing, gathering wild plants, bamboo shoot hunting, 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 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 the adhesive. Regarding the materials: The material used is curly maple. It is a wood characterized by wavy or shrunken patterns (curly grain). It is extremely rare and not readily available. The price of the material is also very high. Details: Body material: Curly maple Barrel: Diameter 16mm, depth about 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. As this is a handmade item, there may be minor scratches, measurement errors, and slight unevenness on the painted surface, but 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.
