They are about the size of horse flies. They look kinda realistic, at a glance. I bought these for Halloween, and i think they'll work just fine. Worth the buy for sure.
My friend had ordered these flies for a promotional dinner. Many of the parents thought they were real. We ordered them as give aways for the actual event.
I loves these flies. Customers use them for fishing and they work!! The size are perfect and so is the price.
