I purchased these for me and my housemate along with the lowercase letters as we've been talking about buying something like this for ages. Good fun leaving each other random messages on our fidge, as stated in previous review, the magnets aren't the strongest, but they do the job fine, and for the price there's nothing to grumble about..... happy to recommend! :)
Also, if you'd like a giggle I would HIGHLY recommend 'Set of magnetic words - fun, suggestive and in very good taste!'.... a set of perfectly innocent words that can be constructed into not-so-innocent sentences.... definitely one for the adults.... hours of fun in those! :)
