The pink thing is for cleaning you cutting mat with after each use. I have a blue one just like it that I bought from the LQS. The two white things are for free motion quilting. Eleanor Burns calls those her steering wheel. I have a gray one, but don't use it much at all. The other little gidgit is a rotary cutter blade sharpener. You take apart the two pieces with the handles on them and then place the blade on then and screw it together and then you put it in the corcular thing and then you twist it back and forth and then turn it around that polish the blade on the other side of the round thingy. I've had mine for years, but don't like it. Have a great day, Huggies, Fay
