Use to dispense gutta outliner, thick paint, masking fluid or glue.
The long plastic spout can be used as it is or cut down so that the screw on nib can be used. The thread on the nib screws into the plastic for a secure fix. The 20ml bottle comes with one 0.6mm screw nib and a fine wire for cleaning the nib.
Our additional images show the 50ml bottle with nib attached.
