This is a magnifier made by Bohin that has a clip on the end of it that will fit your table edge, your Evertite stretcher bars and maybe even your floor frame (depending on the type you have.) The magnifier glass is 5″ in diameter and a protective white storage bag is included. The flexible neck is 18″ long – wow! That will stretch over nearly any large piece you’re stitching. Note: This is heavier than the small clip-ons that we’re used to and is suitable for large projects or to be clipped onto a sturdy frame or holder.
