MICROELITE Sewing Machine's Three Major Features: (1) Thick fabric sewing - Easily sews through 12 layers of broadcloth. (2) Stitch width - From 1mm to 5mm (a first for a compact sewing machine!) (3) Bobbin thread adjustment - Newly designed automatic mechanism. Just pop in the bobbin. You can enjoy sewing with any thread without adjustment. This product can be used with both batteries and charging. Operation has been confirmed, but the sound is quite loud when it's running, so it's best to apply oil to the sewing machine before using it. An instruction manual is also included. However, since it was measured by someone who is not a professional technician, the actual performance may differ, so please refrain from purchasing if you are concerned about this. The wooden box may have scratches, but please judge based on the photos. Please avoid this if you are a perfectionist.
