Was surprised to see them come in a flat envelope but was a breeze to hook together. The 3  long containers work great
for an underwear drawer. The 2 med size containers work great in Bra drawer and the large 9 compartment container worked good for my sock drawer. I was able to stuff two pairs of socks in each square. I'm thinking I need to get another set for my hubby. Love how organized my drawers  now look!
