Dear Mr. Daniel,
Thank you for contacting us and for your inquiry.
For your reference, our products are suitable for Polyester and Cotton but we do not recommend applying them on Silk.
We are not certain what the foil for printing on garment is as we have various types of products.
So it would be appreciated if you let us know the name of the product for us to assist you properly.
For further inquiries, please contact us through our email firstname.lastname@example.org
Then we will get back to you promptly.
Dae Ha Admin.
