    Une belle découverte

    Première fois que j’essaie les culottes menstruelles et j’aime bien ça. Je les trouve très bien et de bonne qualité. Seul bémol à date me semble que le tissu n’est pas très gainant, je les aurais imaginées plus serrés. J’espère qu’elles vont rester en bon état longtemps malgré le tissu plus mince.

    Not right fit for me

    The quality of these undies seen to be quite good. I’m giving them 2 stars as the size was not comfortable

    (Too big) therefore unable to give a proper review. I’m ordering a smaller size in hopes they will better fit me
