1.5 litre nuc round rapid plastic feeder with one central hole.
Bees come up through the hole and over the dome. A cup/cone over the dome allows feed to flow into the central area but prevents bees from escaping into the feeder. The cone has ridges to give the bees grip.
Clear cup allows you to see bees whilst feeding
Capacity approx 1.5litre
Can be refilled with ease without removing it from the hive
