The project is being marketed as “the Future Gadget Lab’s first exhibit at ComiMa,” ComiMa being the in-universe equivalent of Comiket. According to the official website (Steins;Gate and Steins;Gate 0 spoilers are present in this link), the exhibit will be held at Hall A, booth #1323. What will be sold at the exhibit is still unknown aside from a vague hint stating that the products have been created with “Lab Mem’s wisdom.” The website states that further details on what will be sold at the booth will be revealed later. Additionally, those who spend 5,000 yen or more (approximately $46 USD or €42) at the exhibit will be entered into a lottery, the prize for which is also not yet known.

UPDATE: The project’s official website (Steins;Gate and Steins;Gate 0 spoilers are present in this link) has been updated to list merchandise that will be sold at the booth, which includes (but is not limited to) a brand new T-shirt, Lab Member pins from Steins;Gate and Steins;Gate 0, and reproductions of Moeka Kiryu’s used glasses cleaning cloth.

Items that will be distributed via lottery have also been listed on the website. These include a Kurisu-themed alarm clock, Steins;Gate-themed QUO cards, and Steins;Gate-themed acrylic keychains.
