The Teranishi Guitar Aurora Ice Blue Glass Dip Pen combines a removable glass nib with an acrylic resin barrel and protective cap. Its spiral grooves retain ink while writing, while the easily rinsed nib makes changing colours quick and simple, making it ideal for ink testing, drawing, creative writing and shimmer inks.

The Teranishi Guitar Light Blue Glass Dip Pen is a handmade glass pen for writing, drawing and sampling bottled inks. Every pen has its own unique pattern: the balance of light blue and gold-toned sparkle varies, with golden highlights more prominent in some pieces. Dip the grooved nib into ink and rinse it with water when changing colours. Photographs are illustrative: the pattern and balance of colours on your pen may differ from those shown.
