    3.0 out of 5 stars Not Universal
    Reviewed in the United States on May 14, 2022
    Verified Purchase
    Korky always makes quality products and normally work just fine. For these though, they are not universally fitting. I have a dual flush, top flushing single unit toilet but these do not fit. The inner circles on all three were too small and the outer circle too large. Be sure to measure your seal to ensure these will fit appropriately.
