The largest of all my fillable lamps, this recycled glass base has a removable cork top so you may add your own collections. It has a wide opening of about 3 3/4" so large shells can be placed easily. This is also a gorgeous base to fill with dried flowers or just leave it plain as the slight green tinted glass base has a rippled effect. The silver cord comes out of the side of the socket and it has a 3 way light switch. The hand cut & pierced sea shell design lampshade is made on cream paper and comes with a real shell finial.
