We use a commercial grade transfer material that is "not" card based. This means once ironed on correctly, you can wash your tops and even iron them (inside out) with no problems what so ever.

Washing Instructions for Iron on Transfers
- Wash at a 40 degrees temperature
- Do not Tumble Dry (this will make the letters look wrinkly)
- Iron garments inside out with no steam
