Used Insect Substrate Bottles Bulk Sale [Price Reduced Now]

I'm starting to move beyond raising larvae, so I'm selling these items in a bundle.
Some were purchased new and have been used for several years, while others were bought on Mercari, so there's a variety.

I've included a measuring tape to indicate the size, but please consider these as approximate measurements.

Larva rearing bottles (small, clear plastic)... 8
Larva rearing bottles (large, clear plastic)... 10
Replacement filters for large larva rearing bottles... 5

Besides filling them with spawn, these bottles can also be used with substrate to house beetle and stag beetle larvae partway through their development.

There are many signs of larvae having scraped the inside.
Many parts appear cloudy white.
These are not recommended for those seeking new or pristine items.

For shipping, I will use recycled cardboard boxes and newspaper from supermarkets, etc. This will be simple packaging.
Items that can be stacked will be stacked to save space.
