As per title - stainless steel - 4 teaspoons for 0.30p.
Found in Edmonton branch of ASDA.
I know most supermarkets do cheap cutlery like this but I've not seen spoons at this price in any of them - and it's the selling price (not marked down). They are quite basic and nothing special, but for the price you can't go wrong for everyday use.
I cannot find these spoons online so it is most likely instore only.
