We wholesale spawning logs for stag beetles in Kagawa. These spawning logs are used every year and have a proven track record! Not too soft, not too hard, they have been used successfully for spawning various species, both domestic and foreign, including Dorcus hopei binodulosus, Dorcus titanus, Prosopocoilus inclinatus, and various other species. The logs are from shiitake mushroom cultivation, and are carefully dried in a warehouse for a year. Our spawning logs are mainly made from Konara oak. We try not to sell logs with insect damage, but there may be oversights, so please understand. We hope we can be of some help to your breeding efforts. Thank you for your support, even if it's just for a short time. ☆Product Details☆ Product Name: Spawning Logs, 9 pieces Size: 6cm diameter, 13-14cm length
