Uni-ball Eye Micro Rollerball UB-150
£2.50
The UB-150 model features a strong blue colour for ink, a removable cap and a clip so you can carry it around while it’s secured. The gel-based liquid ink is dispensed through a nib that is 0.5 mm in width, which in turn leaves a 0.3 mm line you so can write with fine precision. Features uni-super ink that is fade, water, UV and chemical proof.
