Dimensions are approximately 1.5" high and .25" thick. Their width varies, depending on the letter itself (imagine the I vs a W).
Letters come speckled with various colors; each will vary in colors and looks as each piece of plastic used is different. No two are alike! Occasional small bubbles may be apparent in the letters; we choose to think of them as bubbles from the sea!
These should not be used as toys.
