Before shipping, we sent you product photos for your confirmation. Based on the pictures you sent us now, our engineers replied that your cartridge was modified, but you did not tell it to us when you inquired about it. This is a standard product part number. We ship according to the standard size corresponding to the part number. We have responded positively to your feedback by asking you to tell us the size of your cartridge or if you send us the cartridge, we will produce according to your specifications. But you didn't reply us.

Thank you for your high evaluation of our products,that's what we should do, we also look forward to our next cooperation.
