kwest if you Google for packing cubes you’ll find an enormous selection to choose from. Mine were cheap and cheerful ? I put underwear in one, socks, nightwear, slippers in another, all tops in one, jeans and trousers in another etc. Or you could put a complete day’s outfit in one, they’re as versatile as you could need!
They make packing so easy, everything is to hand so no more rooting around trying to find something. I also use a small cube for adaptors and chargers/charging leads.
