NWOT 5 Oral-B replacement heads

These are unopened and unused Oral-B replacement heads. They were originally 8 heads in a pack and I bought them from Sam’s Club. I just recently switched to a Sonicare and cannot use these anymore. These are the floss action replacement heads, but I believe they can be used with most Oral-B electric toothbrushes except the Sonic, Pulsonic and battery powered brushes.
