Good morning This is the second time I buy from you. The first time I bought the yellow one and I was very satisfied. The second time I bought the black one that arrived yesterday, and to my surprise it is not the original cartridge, but an HP cartridge that can be used in the machine but does not adhere perfectly to glass. I can buy this model they sent me here in Brazil much cheaper. I bought it just because I thought you only worked with original cartridges. Even the box came with the seal broken, closed with adhesive tape and just the part of the seal where the expiration date was supposed to be, the part was removed. I am very disappointed with this purchase and would not want to portray this on your social media. I await a decision on the case. Thanks Leonardo de Oliveira
