This exists, you can actually buy one. We will custom make the t-shirt for you in a small factory in Germany, Marvin will sign it and then directly ship it to you.
This is a Pay-What-You-Want item. The minimum price for this item is the price with standard worldwide shipping from Germany, not tracking just the cheapest we can get.
Everything you pay more than the minimum price is considered a donation to Isabelle and the community and will be used exclusively for that.
If you don’t want it signed, let us know in the order notes.
