$10 seems a little high for what it is. I'm not aware of any like it. I just use very small tuperwear containers with lids. Thaw, strain through a brine shrimp net and dump back in the container for feeding or storing in the fridge for later. I rinse the net in the tank to let the small stuff feed corals. The containers are dedicated for fish food so I don't even bother washing them, just rinse and toss under the tank.
