Sorting through my grandparents' belongings.
There are many items, so I am listing them little by little over time.
These are mainly my grandfather's belongings, who had many hobbies, so I do not have specialized knowledge. It will be difficult to answer questions. I will consider lowering prices on older items once I have listed a certain number.
