Absolutely the best netting I have found and ever used. Softer than silkworms, pliable, vinyl mesh great for netting medium to jumbo sized silkworms. Lay the netting directly on top of them, put your leaves or chow on, let the silkworms crawl through the netting, and LIFT! Place directly into another container with the netting and it becomes a frass separating mesh! Absolutely AWESOME, easy to clean, and labor saving.  Comes in a large sheet 3' by 1.5' . You may cut to size and use several at a time as a transfer medium..
