Non-standard cards that can be used to pick out the keys

    Our standard card size is 85.5*54*0.76. If it is larger or smaller than this specification, we will use molds. This is called a non-standard card. Unlike other non-standard cards, the first image we see is a standard PVC card measuring 85.5*54*0.76. However, it requires four streaks to be pressed out in the middle of the card. After pressing, the card inside must not fall off, and the card must be smooth and clear. When using the small card, you can gently apply a bit of force to remove it, which is a huge test of our craftsmanship and technology.
