I am selling this item because I purchased it twice. This is a Japanese-specification ultrasonic cutter. It can cut and carve plastics, wood, and other materials very cleanly. I use it to cut support materials from my fused deposition modeling (FDM) 3D printer. I haven't tried it yet, but I've heard it can also cut thin acrylic sheets. I think this is a must-have item for those who use plastic models or 3D printers. It is the JM-Y10 PRO version ultrasonic cutter, so multiple replacement blades are included. 30° pointed blade x 10, 60° pointed blade x 10, 30° narrow pointed blade x 10, Horizontal blade x 10, Thin chisel blade x 10 Hex screws x 5, Cut-resistant fingertip gloves * 4, Blade protection case x 2, Magnet pad * 1 Blade holder x 1, H2.0 S2 Hex wrench x 1, 1.5m Type-C charging cable * 1, JP power adapter * 1 Grinding rack * 1, Grinding stick * 1, Dedicated case
