KOINOBORI CHALLENGE - Aaron Wang

Up for auction is one my leftovers from the IPP Puzzle Exchange 2025 in Tokyo. It is a disentanglement puzzle called KOINOBORI CHALLENGE designed and manufactured by Aaron Wang exclusively for the mentioned annual event. As it was an exchange puzzle, it is not the typical highly difficult brain teaser but manageable for the seasoned puzzler. The item is in new condition.

After the auction ends I will pro-actively contact the buyer and provide shipping options via Deutsche Post / DHL or Hermes. After the preferred way of shipping is clear, I will provide final payment amount.

Payment Options:

Generally I prefer cash or SEPA payments but many buyers from overseas do not have this possibility which is why I am willing to accept payment via Paypal. In the latter case it would be great to receive the money via F & F option to avoid fees but this is up to the buyer of course and no "must".
