Crushed, I take a different sites cover or fill in my hamster cages. Also you can tinker with it well, for example rooftops embellish, simply apply water-resistant wood glue, can sprinkle and dry the Terrano Cork crushed. So you can also order other hamsters accessories shape. From hobby I have a lot of products and have been always satisfied. Therefore, 5 stars from me and yes, I'll buy it again.
