Transformers TCG Card Cover

Some Transformers TCG character cards have one side split into two modes. This cover allows you to easily mark which side is active. This cover slides smoothly over a [BCM 3.5"x5" top loader case](https://www.bcwsupplies.com/3-5x5-topload-holder).

**Note**: [Ultra Pro 3-1/2"x5-1/8"](https://www.amazon.com/gp/product/B000VVCPUG/) are too large for these covers. To support that, the size would need to be increased.
