OXO Good Grips POP Accessories is a brand-new line of tools designed to help you make the most of POP. The OXO POP Brown Sugar Saver is a reusable terracotta disk that brings an end to rock-hard brown sugar by keeping it soft and fresh. To use: soak the Saver for 15 minutes, pat dry and then secure to the underside of the POP Container lid. Re-soak as necessary to keep things fresh. Do not wash with soap.
