We wholesale spawning logs for stag beetles in Kagawa. These spawning logs have been used for spawning every year with excellent results! Not too soft, not too hard, they have a proven track record of spawning for both domestic and foreign species, including Dorcus hopei binodulosus, Dorcus titanus pilifer, Prosopocoilus inclinatus, Hexarthrius parryi, Rhaetulus crenatus, and Odontolabis westwoodi. The logs are from shiitake mushroom cultivation, and are carefully dried in a warehouse for one year. Our spawning logs are mainly made of Quercus serrata (Konara oak). We try our best 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 for a short time. ☆Product Details☆ Product Name: Spawning Logs, 12 pieces Size: Diameter 5cm, Length 13-14cm
