It appears the for the moment we have the last 5 left as they ran out at the supplier. You cannot select the size at most of the surplus items, you write the desired size or equivalent in the "Notes from customer" section of the online order. This is because we get surplus items in bulks and we don't know what sizes we get until we get them and sort them. So, write the desired size and our colleagues will search for an equivalent.
Hope that helped.
