Maison Dandoy available in England?

Hi Belgians,

I know this is probably a long shot but is there any chance I can find these biscuits in London/England?

My employers, who are Belgian, bought these for me a month ago as a leaving present and I absolutely NEED to find and buy these biscuits asap.

If I can’t find them I’ll either have to find a Belgian friend or get the Euro Star 🥹
