I am sorry to ask you this elementary question.
What is the black ring in the first picture?
What is the purpose for having it?
Is it ok to add the black ring to the FCT sleeve when I sell it? Or is not to have it better?
Will you also tell me the reason for it?

Is it possible for you to send the picture of the product?

If they sell well I am going to order 3 to 5 pieces each of the following products.
Do you have any plan to stock these?
Is it possible that you can give me any discount if I buy more than one?

Sorry to ask you such a basic question but what is the black ring on the first picture? What is the purpose of it? Is it ok to put the black ring to FCY sleeve when we sell? Is it better not to attach it? If it is possible, I would like to know the reasons as well.

Can you send me some pictures of the products?

If it goes well, I would like to order 3-5 of each product.
Are you planning to stock these products?
Is there any discount if I buy many of them?
