If you're looking for an even more sustainable option, consider a period cup such as the BeYou Menstrual Cup (£15). Menstrual cups can last up to 10 years, which drastically reduces single-use waste over the years. They hold up to three tampons worth and are super easy to clean. BeYou has a quiz so you can even work out the cost saving when using a cup versus a pad or tampon. However, cups are definitely a product that take some getting used to, and isn't an ideal option for everyone, including people who have an IUD.
