This write so well but omg the led of the pen always falls after a few writing and you can twist back on and still it will keep falling out I had to glue mines because I bought the big pack of them and I ain’t gonna just throw the out
I bought these because they said low viscosity ink on the package and it's cheap. As soon as I write I see ink blob. It is low viscosity ink which is nice but the ink blobs make it undesirable.
