Review on 🖨️ Aztech TN227 TN-227 TN223 TN227BK TN223BK Toner Cartridge Replacement for Brother MFC-L3750CDW HL-L3210CW HL-L3290CDW L3230CDW MFC-L3770CDW Printer (Black Cyan Magenta Yellow, 5-Pack) by Tim Harris

The box was tightly packed with 5 toner cartridges. The tri-color cartridges have dots on the black plastic backing to indicate the color of the cartridge. The kit includes a helpful manual to help you replace the cartridges. My printer says "Non Genuine Supplies" but prints with no problems. I've included a color test print to show the quality - it's as good as OEM for a fraction of the price.
