The EN71-3 certificate is a requirement for manufactured toys. As the yarn in our stash is intended for makers who knit or crochet as a hobby, we don't have these certificates - sorry about that!
You can contact the manufacturer directly for more information on obtaining the certification.
Our most popular toy making yarns, Paintbox Yarns, are OEKO-TEX Standard 100 certified and this information is printed on the ball bands of the yarn. More information on this can be found here: Oeko-tex
