CS-8120 the ground-breaking technology incorporated in Brother's premier Innov-is branded product, sets the CS-8120 apart from anything that has gone before. Its unique slot and sew thread cassette system, provides the user with automatic machine threading - completely eradicating the need for manual intervention. Cassettes are simply loaded with thread spool and then slotted into the CS-8120 if users need to change a thread colour during sewing or a bobbin runs-out, they simply reload a different cassette and carry on where they left off. It couldn't be easier! Ideal for larger sewing projects where several colours may be required or for disabled users who may find threading-up particularly difficult. Minimize
