Pressing the plastic base onto the lid, flipping over the feeder and slide partially into the entrance of the hive, the vacuum pressure in the sealed jar will prevent dripping.Features- Color: White. - Material: Plastic. - Size: 14 x 8 x 3 cm. - This bee hive entrance feeder is dense plastic material with a small mouth canning jar metal lid attached. - Much easier to monitor and refill than internal feeders, bees will be happy to eat sugar water from feeders before nearby plants are not yet producing pollen. - Metal lid is perforated and fits plastic or glass canning jars. - Easy to install on the entrance of the hive; the perforated lid is removable for easy cleaning and securing onto the jar. - Dear buyer, Due to lighting effect,monitor's brightness,manual measurement and etc, there could be some slight differences in the color and size between the photo and the actual item.
