Text tutorial

1. Remove the RSVP ink tube, put an insert in the body and keep the backplug in place.
2. Fit the HGG tip and a G2 grip on the front of the RSVP body.
3. Put an 8 mm section of thin grip inside the RSVP cap.
4. At the front, add the G1 or G3 tip over the HGG tip with 1.5 cm of Anyball grip.
5. Add a thin grip over that grip, then arrange 4 mm Anyball, 4 mm thin grip and 4 mm Anyball sections.
6. Add grips between the body and cap so the body stays in place while spinning.
7. Add pewter wire at the front and in the cap to adjust the mod’s balance.
