The Parrot Jumbo Mini Sleeves are the perfect choice for any wood or metal project. These roller covers are made from 100% Mohair, which is a luxurious silky hair from Angora goat yarn. This combination gives you a glass-like finish with all high-gloss or semi-gloss oil-based materials, providing a high-quality, professional finish. The 4.5" size is ideal for those hard-to-reach places and the twin pack allows you to get twice the coverage with just one purchase.
