Got my ff breader speical kit today from Ed's. It came w/ a 4 lb. bag of ED's Super Instant Fruit Fly Media, 3 fruit fly cultures (you can choose from wingless, flightless or curly ?D. melanogaster), 10 - 32 oz. containers, 10 foam plugs, 10 drilled lids, a full 1/2 lb of excelsior and a 1 oz. packet of yeast. it arrived (w/cold pack) perfectly. Flies are in great condition. It has two cultures that are almost mature (so that we can have ff later) and one that is packed full and ready to go now. The cups and predrilled lids are great quality (thick and definitely reusable) and as others have noted the large foam stopper is great! Will definitely purchase from them again.... right now I have more than enough.
