Marvelous Merchandise in Genshin Impact is an event featuring the eccentric merchant Liben. This event has been done twice before, with the second one being different from the first.
For the first event, players should find Liben somewhere in Mondstadt and Liyue. Afterward, they can talk to Liben to exchange some materials for his Box O' Marvel. The reward for the boxes is fixed.
While in the second event, players don't have to look for Liben. He will stay near the fruit stalls in Mondstadt. Players can also choose which box they would like to obtain.

Marvelous Merchandise event in Genshin Impact
On April 13th, Genshin Impact Official announced that the third Marvelous Merchandise event would be held from April 16th to April 23rd. This event will reward players with various things like Primogems, Mora, Mystic Enhancement Ores, and Hero's Wits.
To participate in this event, players will have to find Liben somewhere in Mondstadt. Afterward, players will be required to submit some common items to be traded with a "Box O' Marvels."
Players will be able to see the rewards they will obtain from their boxes before exchanging them. If players do not wish to get that particular reward, they can visit other players' worlds for a chance of getting a different box. After exchanging five boxes, players can open a "Mega Box O' Marvels."

Based on the event description, this Marvelous Merchandise will most likely follow the system of the last event.
This means that it can be predicted that each box will contain 40 Primogems, while the Mega Box will contain 100 Primogems. So exchanging five boxes and obtaining the Mega Box will reward players with a total of 300 Primogems.
Liben seems to love collecting common materials like Sunsettias, Sweet Flowers, Pinecones, Apples, and Bird Eggs. So players should not worry about not being able to fulfill his request.
