New, unopened 7-piece set of BRITA Maxtra+ cartridges. These are replacement filters for water purifiers. One box of 4 is unopened, and the other box has only one used, so there are a total of 7 filters ♡ One bag was taken out of the box, so the color of the bag has slightly changed. It's the one in the lower right of the photo. Please purchase if you understand this. Instant purchase OK.
