Used item: 40-piece set of 800cc clear substrate bottles

Larva rearing clear bottles, 800cc, set of 40.
Sold as a set only, no individual sales.

As shown in the images, some bottles have bite marks and label residue.
They are in relatively clean condition and should still be usable.
This is being sold due to my retirement from stag beetle and rhinoceros beetle breeding.
Please note that bottle cases are not included.
