CoroCoro Comics Series (retired)
The ‘CoroCoro Comics’ series came with the cards woven into the magazine itself, stemming away from the original practice of ‘pack-pulling’, these cards were more ‘peeled’ than ‘pulled’.
To the untrained eye, many would oversee these as fake, or knock-off, simply due to the glossy finish. They also peel and damage differently than ‘pack-pulled’ cards, but this is simply a featured shared by ‘CoroCoro’ and the ‘Vending Machine’ series in particular.
Unpeeled sheets do not come around often. Keep your eyes peeled.
