Great fix for easier cutting and neat drawers
Not only uses less drawer space but greatly improves ability to cut desired length without needing to take it out of the drawer matching bag organizer makes a perfect set long length fits parchment paper and still workdays for standard rolls of foil Now my drawer looks organized and I have enough extra space to store my potholders

Good Holder / cutter
This is good quality build. It cuts well enough. My only issue with it is that Saran wrap doesn't stay on the lip where it gets cut, but that may be the wrap itself, not an issue with the block.

Plastic wrap helper
I use this for parchment paper and plastic wrap. Works good for the parchment paper and it great for the plastic wrap. It is heavy enough so when you pull out the plastic, you can put it over the bowl. Much easier than the cardboard box the plastic wrap comes in.

Unconventional Usage
I use a variety of these SpaceAid Long Wrap Dispensers to hold my stabilizer for my embroidery business. I have a couple of rolls that are longer than most, and these particular dispensers hold them perfectly. The cutter is very sharp and makes cutting in a straight line a snap! They look very nice hanging on the wall too.
