For use with TBH Slim-vent system. Dial in your ventilation\humidity settings with this set of 3 air restrictors. Each one has 1, 2, 3 and all ports blocked except middle and edges on one insert. Add your favorite color of chiffon between the restrictor and vent for keeping what's wanted in and what is not wanted out.

Because we manufacture these ourselves there may be a 7-day lead time needed before they ship out. Please take this into consideration when placing your order.
Vents are awsome
With these vents I can turn any size tub into a bug tub.
Really fun and awesome product, just what I needed for my isopod springtail culture is. I'll definitely be getting more in the future.
