These are Taylor Seville Originals Comfort Grip Magic Pins fork pins, a pack of 30 fine pins with a storage case included. Each pin measures 1.75 inches long with a fine 0.5mm shaft, and the heads are purple. Fork pins are a specialised shape — the split, two-pronged tip grips fabric from both sides of a seam, which holds seam intersections and matched points in place far more securely than a straight pin. That makes them the pin quilters reach for when nesting seams or aligning block corners that have to land exactly.
The comfort grip heads are the other half of the design: a larger moulded head is easier to pick up off a table and easier to hold onto while you work, which matters over a long piecing session and matters more if you have limited hand strength or dexterity. The heads are also heat resistant, so pressing over them won't melt or deform them. Pins and case are made of metal and plastic, and the case closes to keep the set together. This listing includes 30 pins and the storage case only; no other notions are included.
