I bought these hoping they were similar to my old sleep mask which had finally said, "Srsly? Sleep when it's dark like normal people," right before it fell apart.They are exactly the same.~~~The easiest way to describe the design is that it's like a small bra. It may sound weird but, if you think about it, it makes sense.There's no extra material added inside to keep the mask up off of your eye lids. Instead, it's just firm enough to curve over your eyes naturally...like cups. But it's soft so it doesn't scratch, and you determine the tightness with the velcro strap.I don't remember the description saying this, but they come with a satin, drawstring bag and a pair of earplugs...like something you'd find on your pillow in a B&B, motel, etc.. (Should have two pairs of earplugs though. One pair for each sleep mask.)These are definitely worth the money, they're comfortable and, most importantly, they work.I have purchased another brand of masks and these are by far the best sleep mask. They fit perfect and let in 0 light!! They are soft and comfortable. The only complaint is that the elastic starts to grow and I have a small head so eventually to gets so loose that I have quite a bit of overlap to deal with when making it tight. They also come with ear plugs and case and satin bag for the mask. Don’t hesitate to purchase these masks.I love how these sleeping masks have just enough presence/weight on my eyes that I can barely stay awake once I put on this mask. The cupped area for the eye is fantastic and it does not let any light through. This is the second set I have purchased, I got a solid 14 months of use out of one pair.My son likes a nightlight in the hall but it was really impacting my sleep. So I bought these on a whim and they have been amazing! I feel like I’m sleeping so much harder.Cover eye well so light don’t get in but not as soft as I would likeI don’t know who’s doing quality control for the company but they need to pay attention more. Both pairs were supposed to come with earplugs and an eye case. They were missing one eye case and set of earplugs. I didn’t pay for a partial order but unfortunately that’s what happensI really have no complaints. I worked nights for a long my time and ran through my first set in about a year or so. I recently bought again and sleep with them almost every night. Comfy and the little eye scoop holes don’t press on my eyeballs!I have to say, I am very pleased with this sleeping mask. I haven’t liked any others that I have ever worn. What I really like is that it has the space for your eyes so your eyelashes don’t get squished and you can open your eyes. I was also worried that I would end up with a dent or crease where the mask rests on my cheek but that didn’t happen either. Would highly recommend.The mask is very soft but has ability to hold its shape which is contoured on the inside to make room for your eye lashes. Great if you are naturally gifted with lashes or if you use falsies.I love this sleep mask. It is really confortable and block the light really good. I put a picture of the drug store sleep mask I used to wear for sleeping. As you can see the rubber band is sturdier on the 3D Sleep Mask, the drug store one broke easily. The 3D sleep Mask took the shape of my face to prevent any light to come in, the drug store one I could really see light at the bottom. For the price it is hard to beat you get two mask. I'm really satisfy with my purchase and it make my night better.My window is on the side of the house and the morning sun shines in brightly at around 7:00am and wakes me up. I have dark blue drapes but they don't work all that well. I bought this mask to help me sleep in, however it didn't work out. The padding that wraps around your eyes doesn't really let your eyes breath all that well, I was sweating and hot. The strap is an adjustable velcro strap, if it's snug enough to hold the mask in place it feels too tight, if you loosen it up the mask shifts all over the place, I tried loosening it as much as I could without the mask falling off but it was difficult to keep it in place and I still woke up with a headache. Other reviewers rave about it so that is why I bought it but after one night I learned sleep masks are not for me. All that aside if you position it properly on your face it does block out all light. I doubt I'll use it again, instead I am going to buy better drapes that will block out the morning light.Product description, packaging, etc all state 2 sleep masks, carrying case, and earplugs....all I got was 1 black sleep mask.I will be emailing the seller. I'm not against this price for 1 excellent mask, however, the item(s) should be as advertised for the quantity.Edited to add: I emailed their customer service with photos (last night at midnight) as per the provided info card inside the box and they responded by the time I woke up this morning. They provided me with a discount code for Amazon to order a new set. Amazing customer service, I am happy.I used the product today...excellent light block out and very comfortable and adjustable strap.This is a life saver after a night shift in the summer. Trying to sleep through the beautiful sunshine is a hard thing to do, but this makes a huge difference to my sleep quality when it's light out. Comfier than I thought it would be too, doesn't interrupt my sleep at all.
