The material used is red cedar. The hollowing is done almost entirely by hand, so there may be some slight errors. Please understand. The error is about 1-2mm. Dimensions: 84mm (height) x 158mm (width) x 85mm (depth), 58mm (inner depth) Weight: 280g Magnets: 4 neodymium magnets are used. The magnet holes are filled to prevent rust. Includes: Main bait box, 2 Tajima Seif (safety hooks), simple instructions, and a Tamo Kobo sticker. The bait box lid and body are made from the same patterned lumber. It is handmade, so there may be some areas that appear slightly distorted or uneven. It is not as perfectly finished as a machine-cut product. If you like it, please consider purchasing. Please check the 8th photo for the paint finish. The screws on the male side of the Tajima Seif SF-BHLD are secured with two screws. Please check the 10th photo. Thank you.
