You may need this if you'd like to add a random amount of items top your order. It is like to attach an additional postage stamp.

This is how it operates:

1. You order a Pro-Liner HD Intl Eng 2020 item. It covers the basic delivery price for one item;

2. You add any number of additional Pro-Liners HD Extension or Personal Bodygraph Compass. They are not available as stand-alone item.
