This is a listing for a total of 20 used insect culture bottles: 9 bottles around 800cc + and 11 bottles around 600cc. ★ The 800cc bottles are labeled as 1000cc on the original box, but are being advertised as 800cc+. There are two types of bottles, but they look exactly the same. These were used for raising stag beetle larvae and adult beetles. ★ Glass bottles do not sweat, so the mycelium degrades much slower. The temperature inside the bottle is more stable than in plastic bottles. ★ Unlike plastic bottles, glass bottles do not deteriorate, so you can use them indefinitely. ★ As these are used bottles, there are bite marks from larvae and scratches on the underside of the lids, but they are still perfectly usable. ★ These are clean bottles. ★ Some bottles still have stickers attached, but they can be easily removed with benzene, etc. ★ Most bottles do not have Tyvek seals. Please be aware of this. ★ Ideal for raising adult beetles. ★ Thoroughly cleaned. ★ Please understand that these are used items, and those who are overly concerned should refrain from purchasing. Shipping will generally be on Saturdays and Sundays. If possible, we will ship immediately. Please understand. ★ We will overpack the bottles to prevent breakage. Please understand.
