This is a marketplace by collectors for collectors. Collectors offer their surplus collectibles. You can usually buy them cheaply or acquire them through barter. In the overview you can see items from all collections. Through various filters you can narrow down the display. After you have selected your items, your request will be transmitted to the supplier. This person will get in touch with you. The purchase or exchange takes place directly between the vendor and the interested party. You can transfer the data and object history of your purchased items directly into your free Geolitho collection management.
