- Eight hour hold

Your first 90 nights
It is a habit. Here is how it forms.
Nights 1 to 7
You notice it
The strip feels new for a few nights. Keep the skin dry before bed and peel slowly in the morning. Some people take it off once in the night and put it back on. That is normal.
Night 30
You stop noticing it
Reaching for the strip becomes part of turning off the light. Waking up without a dry mouth starts to feel normal.
Night 90
The next box arrives
Your renewal ships before the last strip is gone. You get an email a week before it leaves. If you want to skip a box or change the date, you can do it from your account. Cancelling works the same way.
In the starter box
Ninety nights of tape. Thirty nights of backup.
- Three packs of 30 strips, black, with the breathing slit
- 30 nose strips for the nights your nose needs help
- A one page guide to the first week
- Anything you added: nose vents, prep pads, the tin

How to use
Three seconds before bed.
- 1
Dry lips, dry skin
Pat the area around your mouth dry after your evening routine. Balm and moisturizer stop any tape from sticking.
- 2
Rest your lips, place the strip
Bring your lips together without pressing. Center the strip so the slit sits over the line of your mouth, then press for a second.
- 3
Breathe through your nose
In the morning, lift one corner and peel slowly toward the center. Give it a week before you judge it.

Questions
Before the first night.
Who should not use mouth tape?+
Do not use it if you cannot breathe comfortably through the nose, or if you have a cold or blocked sinuses. Skip it after alcohol or sedatives. It is not for anyone who has been told they have a breathing disorder during sleep, and it is not for children. If you are unsure, check with a healthcare professional first. Stillseal is a comfort product, not a treatment.
What if my nose blocks in the night?+
The slit in the middle lets air through, and the strip peels off with one hand in a second. The starter box also includes nose strips for the nights your nose needs a little more room.
Does it hurt to take off?+
Lift a corner and peel slowly toward the center. The adhesive is made to hold overnight and let go in the morning. If your skin is dry and free of balm at bedtime, the morning is easier.
How does the membership work?+
Your first box is $79 and covers 90 nights. From then on a new box ships every 90 nights at $59. You can skip a season or cancel from your account page, with no calls and no forms.
What if it is not for me?+
Write to us within 30 nights of delivery and we will refund the first box. You do not need to send anything back.
How long does shipping take?+
Orders leave within three business days and reach US addresses in 7 to 15 days. Every order comes with a tracking link.
