(M) Medium Size 16mm
Among a batch of marbles, some can be 8-12% smaller, others larger in diameter. Most marbles are molded using opaque glass (cannot be seen through) and frequently have surface indentations on their surface (known as 'smiles'). This is an inevitable side effect of the manufacturing process. Colours may also vary, marble making is not an exact science!
