It's B00KDOKQZC on Amazon. I have one coming soon. Three pack, each one supposed to be good for a month.
This afternoon I noticed my nose is peeling, like a sunburn, but not from the sun, from the abrasion of the ffm I was using last week.
I'm using the P10 pillow now, but still have the ffm as a backup.
Would like to have the ffm be comfortable, and work, when/if needed.
I haven't used them, but good luck finding comfort
I started using them this year and they really work great. I will not use any other. I wash them in baby shampoo and get up to two months per gasket.
The only minor issue is that they block the vision totally.
I REALLY LIKE THEM AND HIGHLY RECOMMEND THEM.
