Shur-Line Roller 4" Foam Mini Refill 10-Pack

High Density Foam provides an ultra smooth finish with minimal stippling and bubbling. Foam rollers are especially absorbent, which translates to taking in a larger volume of paint than a traditional roller making them well suited to large surface areas. Another benefit to absorbing liquids easily is that when the outer surface of the foam is smooth, it redistributes that same liquid evenly.
