DOW FILMTEC Brackish Water Reverse Osmosis Elements can separate salts from water and are produced with an automated fabrication process for precision, consistency, and reliability. DOW FILMTEC RO membranes build on a tradition of leadership in the thin-film composite membrane industry and meet the challenges of higher rejection in lower-pressure operations.

Good and Bad
I really like this. I did have a problem which I told Amazon about. this was not closed and there was sun tan lotion out inside the box about half of this was gone. I thought Amazon would have replaced without me sending this one back but no they did not. any way I do Like the product but will sting and burn really bad if it gets in your eyes which is easy to do it is for the face.

Best SPF chapstick
Scent: Island Coconut, Size: 0.35 Fl Oz (Pack of 1)
This is my new favorite chapstick. It’s a little thicker than I’ve used before but super smooth and not sticky!

Really impressed!
Scent: Island Coconut, Size: 0.35 Fl Oz (Pack of 1)
I use this brand as my daily body sunscreen and love the smell, so I was tempted to buy this lip balm. I'm so glad I did! It smells great, and my absolute favorite thing about it is that it seems to last all day. I wear it with a light lip liner and my lips stay soft and moisturized after a long work day, 2 meals, etc. It does have a bad taste, but not nearly as bad as other brands I've tried. If you do the lip stick trick with your finger its unlikely to get in your mouth, unless you bite your lips. So its been a great protection against lip biting as well.
