from the collection you can buy any number and any balusters of your choice

A baluster is a vertical moulded shaft, square, or lathe-turned form found in stairways, parapets, and other architectural features. In furniture construction it is known as a spindle. Common materials used in its construction are wood, stone, and less frequently metal and ceramic. A group of balusters supporting handrail, coping, or ornamental detail are known as a balustrade.
