Hello all, I think it is time to enter the discussion, as I am a manufacturer of them... As ZuluGula said, they are made in Poland. It is not "just" a bit of acryllic material, as pseudografx said. It requires to design and manufacture quite expensive mould, special punch, boxes with printing. And even then, some fixes are required. Then, sell, wrap perfectly, ship and pay taxes: income tax and VAT. Are you sure that do you want to take $10 for all of it? Including your income? . And to invest not small amount of money, risking that you may loose?
One batch of covers may be 70-100 pieces, because I am not able to sell more within a reasonable period of time, and, I would need to rent a warehouse for keeping stock of thousands of covers.
Guys, please, prior to writing such stupid things, think twice. Otherwise I may start thinking that my work is unnecessary and all of you treat me as a scuff only. Thank you for your attention
