Models Own Acetone Free Nail Polish Remover is so convenient as it contains a sponge saturated with nail polish remover. No need for cotton pads. Just twist a finger at a time in the middle of the sponge for a few seconds and nail polish is removed easily. This is a compact nail polish remover and there is no risk of accidental spillage.
I prefer Dip & Twist Pots such as this as I can save on cotton pads. Sometimes I may only want to remove the polish from one finger and I feel it is a bit of a waste to use cotton pads so this little pot saves me from the hassle of having to use pads.
