Clean, lint -free rounds that hold together.
Size: 300 Count
I have purchased these organic cotton rounds at least twice now and they are easy, inexpensive, clean and great for a ton of uses, but especially for cleaning around the eyes without leaving any lint in my eyelashes. When you wet them, they do not fall apart, but are still soft. I highly recommend them.

Say goodbye to pesky bites!
Size: 1 Count (Pack of 12)
I recently tried the Mosquito Bracelets, and they have become a must-have for any outdoor adventure. Here’s why I highly recommend these DEET-free, natural, and waterproof bands: These bracelets are impressively effective at keeping mosquitoes at bay. Whether I’m hiking, camping, or just relaxing in my backyard, I’ve noticed a significant reduction in mosquito bites. The natural ingredients used in these bracelets provide a strong and pleasant scent that mosquitoes seem to hate, making them a reliable option for outdoor protection. One of the standout features is that these bracelets are DEET-free, making them safe for everyone, including children and those with sensitive skin. They are made with natural ingredients, which gives me peace of mind knowing that I’m not exposing myself or my family to harsh chemicals. The waterproof feature is a game-changer. I can wear these bracelets while swimming, sweating, or during rainy weather without losing their effectiveness. This durability ensures that I stay protected in various conditions, making them perfect for summer activities and trips to the beach or pool. Each bracelet is individually wrapped, which is incredibly convenient. I can easily toss a few in my bag, car, or camping gear without worrying about them losing potency. The individual packaging also makes them perfect for sharing with friends and family during outings. The bracelets are soft, flexible, and comfortable to wear. They are adjustable to fit any wrist size, which is great for both adults and kids. I’ve worn them for hours without any discomfort, and they don’t irritate my skin. I was pleasantly surprised by the longevity of these bracelets. Each band provides up to 72 hours of protection, which is fantastic for extended outdoor activities. This long-lasting feature means fewer replacements and more continuous protection. Considering the effectiveness, natural ingredients, and convenience, these mosquito bracelets offer excellent value for money. The 12-pack ensures I have enough to last through multiple outdoor adventures or to share with others. In summary, the Mosquito Bracelets are a fantastic solution for anyone looking to stay protected from mosquito bites naturally and comfortably. Their effective repellent properties, DEET-free composition, waterproof design, convenience, comfort, long-lasting protection, and great value make them a top choice. I highly recommend these bracelets for their overall quality and performance.

Worth a try
Size: 1 Count (Pack of 12)
Not perfect protection, but fewer mosquitos in the past two weeks. I use them in my study where I'm most likely to sit still -- one down low on my desk chair (reduces ankle bites), one on a door knob, one on a corner of my desk. I don't wear them often because I find them uncomfortable. Can't report yet how long they last. Odor is not overwhelming or unpleasant.
