NEEDLE THREADER BY PUFFIN / MAGNETIC
This Needle Threader by Puffin has a magnet on the back. It is intended to attach to your needle nanny & removed to thread a needle.. No more digging for your threader! The Threader is designed for long eye needles and will easily handle those thicker threads and yarns in addition to regular threads and floss. It's available in Puppy, kitty, heart, bee, sheep butterfly, bird, birdhouse, cupcake or whatever I have left in stock. Magnetic Micro threader is also available for threading beading needles.

The threader will fit Long Eye Needles:
Tapestry 28 (beading size) & larger (needle size smaller 18 - 28)
Chenille 28 & larger
Darning 5 & larger
Embroidery 7 & larger
Basting 7 & larger
I too am confused. Think they are referring to the eye of the needle which gets larger as the needle size # gets smaller.
