These Classy Caps are just beautiful. I originally ordered 3 white Japanese style from the company Classy caps. They included 6 batteries 2 for each lamp, and the adapter to fit a smaller post. This set of 3 from Wayfair did not include the batteries nor the adapters. I need the adapters to fit a smaller post.  I have contacted the company Classy Caps to see if I can purchase the 3 adapters and I am sure I will have to pay for them since I purchased their lamps from Wayfair. I would recommend these beautiful lamps to anyone , but not from Wayfair. Purchase them from this company Classy Caps.
