I've always been skeptical of buying polypropylene rugs online because I haven't liked how fake the ones I've seen in person look and feel... normally super shiny and not soft. This rug is polypropylene material BUT I am super impressed with it. It does have a little bit of sheen but I think it's not super noticeable, maybe bc of how thin it is. I think it's beautiful and I'm so so happy with it!
