We require hot stamping foil specifically designed for single-size printing on the back of cardboard material. The foil must maintain clear imprint quality on cardboard surfaces and be suitable for industrial stamping applications.  

Please confirm if your products can meet the following:  
- Compatibility with cardboard substrate  
- Single-size adaptability for printing boards  
- Durability after stamping process  

Additionally, we need to know if you have local representatives in Mexico to facilitate communication and logistics arrangements.
