All Purpose Foot
The all-purpose presser foot is used for general sewing on most types of fabric.
With a clear view section in the front making it easier to sew acuratly.
Leveling button on the side levels the foot when going over bulky seams, this function only works if the snap on adapter has a hole for this to click into (see 2nd photo) - Brother machines have this on the left not right.
Will fit on most machines that take snap-on feet.
