It’s the same as Kokoist, also available on Temu n AliExpress, be careful not to get too much alcohol or water on magnet ends, glue broke down and the magnet fell through the empty barrel onto the other end, making it less strong n have weirder magnet angle n pattern… prior to flopping, strong very strong with good sharp magnet pull.
it’s only so long so the magnets don’t affect each other, awkward length, poor construction. Edges are sharpish, ugly to see magnet on both ends.
