      1. Bella says:

        Please do not worry, no character like “grow”

  15. Jim says:

    What does the “please pay attention” bit in the shipping to Ireland section mean?

    1. Bella says:

      To Irland, it’s 22oV/EU Plug

    2. hello says:

      It might be because the products that they send from the EU have EU 2 prone plugs as Ireland uses UK 3prone plugs, yet we are in the EU. It just that we were part of UK and we never switched over but all EU plugs will work with a single simple EU-UK pkig adaptor.
