Pick any four letters for your set of magnets. Popular choices are two sets of initials or 4 letter words as shown here; 'boat', "surf", "love", "sail" & "fish". Buy a set for yourself and buy a set for your boating friends. All magnets are approximately 2" square. Guess what? If they fall off your refrigerator, they will most likely break because they are glass! Spell anything and Say It With Glass!
