What does it mean when you say that the Thankyou nappies use FSC and FSI wood pulp and have those certifications?

Great question! The wood pulp in our nappies is renewably sourced and is certified by two different groups: for our tab nappies it's certified by the Sustainable Forestry Initiative (SFI) and for our nappy pants, it's certified by the Forest Stewardship Council (FSC). We have copies of these certifications from our manufacturer to ensure that these are accurate claims.
