Beautiful duvet cover but doesn’t have duvet ties

I love this duvet. The fabric and print are very nice. The percale is crisp and lays out beautifully. The negative is that the inside duvet corners do not have any way to tie the duvet into the cover. I just started using this so not sure if the duvet will slide. There’s no mention of ties in the description so that’s on me, but I’ve never purchased a high end duvet cover without them. I recommend this cover but beware it doesn’t have a way to secure the duvet.
