Thank you for viewing! This product is a tool for setting off firecrackers to avoid encounters with wild animals such as bears and wild boars while stream fishing, mountain climbing, gathering wild plants, harvesting bamboo shoots, camping, etc. This time, we have created an integrated, completely waterproof firecracker case. It has no wasted volume and a cool design with high practicality. Since the whole thing is waterproof, the firecrackers won't get wet even if they are submerged in water! ○ About Materials The material used is Hawaiian Koa. In Hawaii, logging on state-owned land is prohibited, and it is currently very difficult and expensive to obtain. It is a Hawaiian native tree that has been highly valued as a sacred tree by the locals since ancient times. It is a rare species that is almost never available on the market. 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 is 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. Details Body Material: Hawaiian Koa Barrel: Diameter 16mm, depth approximately 67mm, all stainless steel pipe Adhesive: Epoxy Firecracker Case: Aluminum (completely 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, 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.
