Aluminum Screen Vented 4.5 inch Deli Cup Lids

4.5 inch aluminum screen vented lids are perfect for housing all sorts of insects.

These are made for the semi-clear (e.g. Fabri-Kal) 4.5 inch diameter cups - they do NOT fit the clear (e.g. Solo) cups.

For fruit fly cultures and other very small insects we recommend the poly-fabric vented insect lids.
