The two things that I hated about the cargo bag, was the protective mat never stayed in place, and flew off somewhere after our third fill up. These "slim fit" plugs are indeed much slimmer than usual, making them relatively easy to insert. Anything will work really. Im sure my neighbors hear me tho. This maintains the support needed for the shelves above, and prevents the shelf from bowing. I ordered an XL since Im very hippy size 14. On that point, the table also backs up about 1/32 of a revolution when it brakes, which I think is a no-no on a DJ table. I am definitely happy with these slippers! Thank you for contacting Bang & Olufsen Support and we will be glad to assist you. These are great for makeup, underwear, for nursery use such as storing diapers and wipes, and even for the kitchen.
