Double and small double duvets (Mowleaze, Barwick)

Could anyone use these summer duvets? The white one is 200x200cm, 4.5 tog warmth rating, has some marks, stains. The yellow one with green leaves is in quite good condition, no stains, slightly smaller, 180x200cm. There's no label on it, but I'd say around 4.5 tog warmth rating.
