PG545XL Black CL546XL Colour Ink Cartridge For Canon TS3450 TS3451 TS3452 TR4650
However it is easy to catch them out. If there are lots of square holes under the sticker it is NOT a real PG545XL. It is a PG545 with an XL sticker on top. The indentations stop them from being overfilled so there is no way they can be XLs.
