BRAND NEW NEVER USED. Bought set of 4 but wanted set of 6 and missed my exchange window. From website: “Messy, over-stuffed suitcases are a thing of the past with the Monos Compressible Packing Cubes. Keep your clothes and other items neatly organized and compressed in our well-structured packing cubes, designed to save space and fit perfectly in your Monos luggage (Set of Four fits all Carry-On sizes; Set of Six fits all Check-In sizes). Unlike traditional packing cubes made of cheap materials that rip or break after a few trips, our compression packing cubes are made to last with all-premium materials. The exterior is constructed with tear-resistant nylon twill, while the interior features the same luxuriously soft, anti-microbial fabric as found inside our travel suitcases. A breathable mesh top panel lets you easily see what’s inside without unpacking, while the anti-catch zippers ensure your packing is always snag-free.” Set of Four includes: 13" × 9.8" × 4.5" / 33 cm × 25 cm × 11.5 cm 13" × 7.1" × 4.5" / 33 cm × 18 cm × 11.5 cm 10.2" × 8.3" × 4.5" / 26 cm × 21 cm × 11.5 cm 9.8" × 4.3" × 4.5" / 25 cm × 11 cm × 11.5 cm
