Neon-Chan Kawaii Mode Card Skin (DEFECT)
Due to the heat from the previous summer month in storage, these cards have shrunken down from their intended size. (See image for reference)
The area for the chip isn't affected by the shrinkage and still fits as intended, but there is no guarantee that it will 100% work with a chip reader.
These defects are mainly for those that seek to use these as decorations or other use cases.
