These aren't a great deal but they do have size 2's Omi https://www.twinkleontheweb.co.uk/acatalog/flexitot-02ft.html
Also, I'm tempted by the offer you posted but I'm not sure I would like them enough to use them. Although, for that price, they will resale well if I got them and didn't like them, I could sell them off individually for more than I paid I reckon.
But I'm meant to be being good with my money haha!
