The Purdy Pail does more so pros can too. 
This pail has multiple grip options, including a flexible bail and coffee-cup style side grip which can help reduce hand fatigue. 
The roller grid and rest fits up to 4.5" mini rollers, adding to job site productivity while a strong magnet allows users to rest their brush in or out of the paint. 
Liners are available separately and provide quick and easy clean-up.
