Both bottles are unsealed. When the bottle is squeezed, air is free to enter and exit the bottle. I have to assume this is a fake based on "asavyseller" selling this. No way how would I ever endanger my animals with unsealed products. Second, if they were unsealed and could squeeze air in and out, they were hand filled, not factory filled and sealed.
