ZENLUSSO bamboo linen have a rich thread count and premium yarn which makes them highly supple. Even if there are wrinkles after washing or storing, they will minimize after being placed on the bed for a couple of hours. We recommend placing them on the bed straight out of the dryer to have a smooth, fresh, amazingly soft bedding to guarantee a blissful sleep. If you need a flatter surface immediately, they can be ironed at a low temperature.
