This is a  Keter Manor Large 6 x 3 ft. Resin Outdoor Backyard Garden Storage Shed. I bought it 3 years ago and it has worked great for storage, however, changes in our HOA regulations require me to sell it. 

New, it sells for about $700 and require assembly. This is fully assembled and only cost $350. Local pickup only. (Please note - This sale is for the SHED only - items pictured in the shed are NOT part of this sale)

Below is the original product description:
