It's the end of a long busy day, can you really be bothered to clean your roller sleeve? You might be using the same paint in the morning anyway. Yes, you could wrap it in plastic which you would put it in the bin when you're through with it but why do that when you could get your hands on a reusable roller keeper?

Durable and easy to clean you can take it with you on every job

Notch in lid means you can keep the sleeve on the roller.

Flexible sides mean you can use it to swap roller sleeves if you need another colour and store the other for later.
