I grabbed these to sort darks, lights, and towels so I'm not hauling one overflowing pile down the stairs anymore. The sides are flexible enough to squeeze onto a narrow closet shelf, and the airflow design keeps damp gym clothes from getting that musty smell.
Three baskets for this price is honestly a steal, and the 27L size fits a full load without getting too heavy to carry. I keep one in each bedroom so nobody's clothes end up on the floor. The plastic flexes when it's stuffed, which I was worried about but it just bounces back.
The airflow holes are a lifesaver for damp towels, and the flexibilty means I can squeeze three into my closet corner without a fight. Sorting everyone's clothes into separate bins has honestly cut my laundry trips in half, and the 27L size holds a full load just fine.
