I would keep it for travel or makeup at home. But if hubby would prefer you to return it.. seeing you gave your mum the mc key holder. Maybe return it and wait until you find something you love to buy again. Collection looks great btw x
I would keep that collection as it is. 6 key holder is more useful to place a card or 2 behind than the 4 key holder and mc cosmetic case is perfect size for what u need...
