Expensive old sewing machines.
Es muy posible que encuentres piesas usadas originales para maquinas de coser domésticas e industriales aquí.. Tienen casi de todo ahí
With a thermal needle that is very layered and informed (the term "Elvin needles")
They have good service, and you can find most sewing machine parts and spares there.
If you take your sewing machine in and explain the problem, they'll fix it, but at what price? After a long wait, because the defect was very easy to fix, they only took 5 minutes to deliver the machine that was 'out of time'. It's true they're experts at fixing that... But charging 700 pesos for five minutes?
