Too Thick to get between teeth!

I wanted to like this floss because it is natural and has no plastic, no PFAS, and easy to recycle. BUT, it is too thick to get between my teeth. It breaks, gets stuck, and hurts my fingers trying to floss. I am very disappointed. I really wanted to buy floss from Radius. Maybe you will have some suggestions for me.

Best Floss EVER

There is no other floss that can actually clean my teeth. It is also made from natural materials. Waxed floss design is thin not allowing the floss to remove the food from between my teeth. My dental hygienist asked what floss I used@

My teeth are very "tight" and this silk floss seems to break. I'll go back to the sponge.
