My flapper started bending and the toliet started running. I ran to the stores to get replacement and the were not working. Toliet was still running. Looked on line for the correct flapper and picked the 2 pack to have a backup. Item fits perfectly! I was able to change it out myself! Thank you for the fast delivery!

At first I thought it was too big but seems to be working fine. Just make if your old one measures 3 inch that the new one does too. The new one is made of a soft playable rubber, makes a good seal. The old one was shrinking in size because the rubber was old and was hardening.
