I ordered one for the test. It came very quickly. The daughters when they sleep, the sheets all turn into a tube. With these elastic bands stretched like a string. I definitely recommend the product. Thank you to the seller. I will order the second daughter.
super! it's my second purchase of this kind of holders. they work well in comparison with the plastic ones. though 1holder is turned upside down (( though doesn't affect the result. sent and received fast.
