rati Nook Trunk Organizer Blocks for Cars and SUVs, Adjustable Cargo Dividers with Dual Grip Pads, Works on Carpeted and Plastic Trunks, Set of 2 Modular Stabilizers

These work very well if you have a carpeted trunk and need to keep boxes or packages from sliding around. The velcro patch covers almost all of one side and does a good job of keeping these things in place. Not useful for securing grocery bags, look for larger foam dividers for that. Made from recycled materials and take up practically no space when not in use.

I have a Weathertech rear cargo protector and these help keep boxes from sliding around the cargo area of my SUV. Work as advertised.

I wasn't sure what to expect but these blocks were exactly the thing I needed. The blocks take a very firm hold to the cargo area carpet. Once placed they take some effort to rearrange.

These are pretty awesome. The Velcro sticks to the carpet very well and it has held my sub in place all day perfectly. Will update if I end up having any issues.

Works great! .I'm using it to keep an aftermarket subwoofer box in my trunk from sliding around. It hasn't moved an inch since I got these on.

I thought this item would not be strong enough, BUT it’s working perfectly

Perfect.versatile !
