Agglomerated Cork Balls

Cork Balls are perfect for general craft use and are often used as fishing floats, keyrings or are even used in the manufacturing of baseballs and cricket balls.

We offer three different types of cork balls to ensure that you have the optimum choice of agglomerated, natural or colmated.

Agglomerated cork balls are manufactured from small granules of cork which are bound together under high pressure to form uniform dense balls.
