Not all silicone
Not pure silicone! I have a corn intolerance (which is in everything!) Used these last night and woke up with swollen sinuses, itchy ears,  and I almost couldn't get the plugs out because my inner ear was swollen so bad. An hour later (after getting them out) and the swelling is going down. Don't get off you're sensitive to things. Thankfully I still had prednisone in my system from a shot 2 days ago.
