It's very simple.
In the menu on the left, there is the "categories" section.
Go there and select any of the three options, click on it:
- Cavas
- Marquists
- Autonomous
- Pirules
- Foreign
Once inside, an alphabetically ordered list of names appears.
Click on the name you want, for example Codorníu, and you will see photos of all the caps from that brand that we have on xapes.net.
Below each photo, there are two red 'buttons' that turn green when you click on them.
- To add a cap to your collection: click the red button on the left.
- If you also have it duplicated, click the red button on the right.
- If you are not interested, you can mark it with the red square.
- If you are particularly looking for it, you can mark it with the star.
