"Unopened Pokemon Card Booster ☆ Players 024 / PLAY Promo Pokemon
It is a prize for earning player’s experience points of 30,000 to 39990 EXP points.
Since the number of issued sheets is smaller than that of Sanders and Vaporeon, it is a very rare promo.
I put it in a file and kept it unopened.
* The bag containing the card has some wrinkles, but the card inside is not scratched.
Even if you look at it with an amateur’s eyes, it is in good condition without white chips, noticeable scratches, stains, etc. Please refrain from bidding if you are looking for a perfect item or if you are nervous about initial scratches.
I need your help by a no claim no return.
In order to prevent mischievous bids, we may cancel the bid at our discretion if you are a little worried, such as a new account, a person with a small number of evaluations, or a person with many bad evaluations. Please note.
When the above person bids, please give us a word from the question column. If you bid without contacting us, we will ship another card.
Even if you have a lot of bad evaluations, you can bid if you contact us, so please cooperate so that you can make a transaction with peace of mind.
Please contact us within 24 hours after it makes a successful bid.
Please note that if you do not contact us even after 48 hours have passed since you made a successful bid and you cannot confirm the payment, we will cancel the successful bid due to the circumstances of the highest bidder.
Since it is a very expensive item, we will ship it by the shipping method with compensation after taking measures against breaking of the card and getting wet."
