SELF-FILLING
MARKING PEN
WRITES ON ANY SURFACE

## Instructions For Filling

1. Unscrew red cap on pen.

2. Dip pen in LABMARK Ink.

3. Press bulb twice.

4. Expell all surplus ink from pen back into bottle by pressing bulb several times. This will prevent leaking. Felt nib in barrel retains ample ink supply.

5. Use like a fountain pen.

## Directions for Extending Nib

1. To adjust felt nib, loosen knurled tapered nut.

2. PULL OUT felt nib to desired length (do not twist).

3. Tighten tapered knurled nut firmly.

## CAUTION

If felt nib should ever be pushed in too far into the tip so felt cannot be pulled out we suggest the following.

1. Remove tapered knurled nut.

2. Use a common, fine steel pin, insert point in one of the slots of the tip and the felt nib can be freely extended.

3. Replace nut and tighten firmly.

**NOTE:** If felt nib is frayed, extend nib 3/8", cut clean with a single edge razor blade. Push nib back to desired length and tighten nut.
