Ikea Packing Cubes
Was in Ikea today (Vantaa, FInland) so you may or may not find them.
They had a pack of 5 packing cubes. They seem quite soft, so I am not sure how much support they will give, but for 10euro for all 5
1 large, 1 medium, shoe bag, and 2 smaller bags.
Seemed a good buy to me - does anyone have any experience of these?
