Pinecone kiln dried pine shavings are ultra-absorbent. They are a medium sized and fluffier than the fine grade. Made from yellow pine lumber with an odor neutralizing fresh pine scent, these shavings are highly screened and have virtually no dust. They are preferred by dairy and horse customers because they last so long in the stall since manure can be sifted very well with a cleaning fork. The bags are well packed 4.0 cubic feet and weigh around 40 pounds.
