A compact, crystal-clear container built for small invertebrate setups. The 155C gives isopod keepers, springtail culturists, and invertebrate breeders a clean, low-profile home for starter cultures, isolation, and small species, with an interior footprint of 4-5/16″ x 2-1/4″ and a 1-3/4″ depth.

Molded from food-grade polystyrene, the walls stay crystal clear, so you can check moisture, count animals, and watch a culture without opening it. The friction-fit lid seats securely and holds a humidity gradient, which leaves the ventilation call to you: keep it solid for moisture-loving springtails and isopod cultures, or add pinholes or a vent patch sized to your species.

The small size makes it a natural fit for seeding new isopod colonies, running springtail cultures for bioactive cleanup crews, isolating gravid females or fresh molts, and housing slings or small feeder cultures. The flat profile stacks and shelves efficiently on a breeding rack.
