Screenshot attached is proof I own all following items I have more outside of the screenshot as well, just chose not to sell them.
(I don't know the prices of items or how much they'd cost, so please be as fair as possible with pricing!)
Note: These items are in random order. I might have what you need, so please do CTRL+F and type in the name of the item and maybe it'll be on this list!
I currently have the following items up for trade and/or sale:
Quantities are not included. Refer to the screenshot for quantities.
I am currently looking for: Lucarionite
I will trade: 1 Masterball and 1 item of choice from the above for the Lucarionite
If you are interested, send me a message of the items in-game (same user TheKippa) or on the forums, or simply post a comment below.
