Up for sale is a 2015 XY Breakthrough Starmie #30/162 graded in a BGS Mint 9. This card is an error with 2 of the four corners left as squares rather than cut correctly.
The card comes as is, the grade being given by a professional grading company and not me. Please feel free to ask for further pictures as necessary. Reach out if you have any further questions.
Happy bidding.
