Kids used to - and still do - like to collect anything and everything (remember Lucky Trolls?). So, when smelly rubbers hit the school scene in the 80s, they became a coveted collectible. Not only did your mum not mind buying them for you - well, rubbers were an essential pencil case item - but they had the novelty factor, too! Each rubber was shaped like something, from a Swiss roll cake to a bunch of grapes and a can of coke - plus they smelled like what they looked. Mmmm!
