Remember the little cardboard boxes decorated like a child's ABC building blocks? Inside were those hard candy alphabet sweets (still sold by the gram). I only ever saw them in supermarkets. I think Marks & Sparks might have sold them in multipacks for a while too. Whilst they no longer come in small cardboard boxes, the same alphabet letters can still be bought by weight today. A traditional sweet shop "Sweet Treats" in Lincolnshire still stocks them today.
