Very nice cotton swabs
Size: 400 Count
Impressed with the quality. It is difficult to open the box and the swabs are difficult to remove as they are packed very tightly.

Great bug repellent
Size: Pack of 25, Set name: Classic
My family and me love these things. We take them everywhere we are going. They work so well and are so simple. Just stretch them a bit and put them on. It doesn't stop them all, but it does a good job and is not some nasty spray that makes you smell funny

Great product for family time outdoors
Size: Pack of 10, Set name: Classic
Great product - exactly as described. No off putting smell (for humans) but we absolutely noticed being less bothered by mosquitos while wearing.

Good product
Size: Pack of 10, Set name: Classic
Very strong citronella smell. The scent lasts much longer than what the product says. Overall better than I thought would be.

Protected
Size: Pack of 10, Set name: Classic
The Cliganic Mosquito Bracelets are amazing to use & are super comfortable. So much so I forget they’re there most of the time. I go to the mountains a lot & during this time of year I get eaten alive by Mosquitos. When I first wore these it worked instantly. I wore one on my ankle and wrist for good measure. My friends didn’t want them because they said “I don’t get bitten” but when they seen how protected I was they were quick to change their minds. Now they buy these too and I don’t go up to the mountains without them.
