Greist Sewing Machine Attachments Box

Vintage box of sewing machine attachments by Greist. These were found in an antique "White" brand sewing machine drawer so I assume that is what they are for but I cannot say for sure. Boxes look to be full but I have no way of knowing if all intended parts are there. Additionally, I do not sew so I cannot tell you what each attachment is or what is included in each box. Each box has 10-12 attachments

Price is for EACH box. 2 available at the time of posting. Boxes are in good condition with some scratching, mainly on bottoms. 

Boxes are apx 7" X 3" X 2"
