Not quite what it seems! A starter pack means the cartridges are only half full or least they should be. While they are genuine Samsung items the packaging certainly isn't. By not being packed in the correct upright orientation the powder certainly starts work it's way out in transit. I weigh check every printer cartridge I receive with the purpose of checking the actual amount of 'powder' inside. After brushing off the surplus on the exterior, I again checked the weight for useable powder and all 4 were under what they should be, one significantly. Not a good buy!
