Thank you very much for viewing this item! ◆ Please read the following precautions carefully before purchasing! ＼(__) ▼ This is a rare, discontinued, and hard-to-find oak wood substrate for laying eggs, infused with Reishi mushroom! ▼ It is made by inoculating fresh oak wood from Mie Prefecture with Mannentake Reishi mushroom and burying it in soil, creating a natural environment. ▼ As shown in the actual product images, the cut surfaces and exterior of the wood are slightly hard due to the Mannentake mycelium and attached soil. However, a toothpick can be inserted into the center of the cut surface, and an awl can be easily inserted, indicating a moderately soft texture! ▼ Images 1 and 3, and 2 and 4 show the cut surfaces flipped upside down. ▼ This is an ideal laying substrate for species that are difficult to breed, such as *Prosopocoilus inclinatus*, *Dorcus regius*, *Allotopus moellenkampi*, and *Chalcodes* species! ▼ It is recommended to use it in a slightly dry laying setup! ● Successful breeding records # *Prosopocoilus inclinatus* # *Dorcus regius* # *Prosopocoilus westwoodi* # *Dorcus kazumiae* # *Hexarthrius forficatus* # *Dorcus hopei binodulosus* # *Grandis stag beetle* # *Miyama stag beetle* species # *Prionurus spinosus* # *Dorcus hopei* # *Dorcus schenklingi* # *Allotopus f. fulrsturferi* # *Aegus elegans* # *Aegus sericeus* species # *Chalcodes* species, etc. ⭐ Oak wood substrate infused with Reishi mushroom 　　　　　　　　　Set of 2 M size! ■ Diameter: Approximately 8.0cm to 10.0cm ■ Length: Approximately 12.0cm to 13.0cm 　　(This is the range from the largest to the smallest dimension of the two pieces.) ◆ There are holes from inserting an awl in several places to check the hardness. Please note that some soil may still be attached. ◆ The wood has been sufficiently aged, so some bark may be peeling off, but this does not affect its use. Please understand and acknowledge this. ◆ Please note that measurements are taken by an amateur with a tape measure, so there may be some errors in dimensions! ★★★ Precautions ★★★ ■ After purchasing, please promptly contact us via the transaction navigation to inform us of your desired delivery date and whether you require time-specific delivery! ■ We will not accept transactions with individuals who cannot or will not communicate, or who are unreliable!
