love how earth friendly everything was, from the packaging to the product 🌏💚 unfortunately I have extremely tight bottom teeth and I'm not able to use this floss on them, but they work for my upper teeth. so if you have extremely crowded teeth like I do this product might not work for you but if you have normal teeth it'll work just fine 🥳 seller was friendly as always and kept me very updated, I love buying from this shop 😊

love its sustainability

I love the idea of all biodegradable and sustainable materials. The case is very cute. But unfortunately, the floss is too thick for me, and it frayed and got stuck between my teeth, so I had to use other plastic floss to get it out.
