Worth it! Get it
Color: 1a. Clear, Size: 72"W x 72"L (Pack of 1)
I was pleasantly surprised at the quality of this shower curtain liner, especially for the price. We have bad water; turns other liners a pinky orange color. This has not turned colors, thick material. And I love how it has magnets to keep it attached to the tub to avoid water getting out onto the floor

Liner Filled with Lots of Light
Color: 1a. Clear, Size: 72"W x 72"L (Pack of 1), Color: 1a. Clear, Size: 72"W x 72"L (Pack of 1)
Basic liner with the added magnets so you are not constantly having to put your curtain where it needs to go to prevent water from your shower escaping and ruining your floor. Does exactly as it is intended and is clear so light is allowed into your shower where you can finally see things and not have to guess. Packaged folded and neatly into a plastic and thick wrapper and all you need to do is open, unfold and install with ease. It fit perfectly into the hooks and the length and width of my shower as the description accurately states. When the time comes for that monthly cleaning, just un-attach and throw into your washing machine and then air-dry and it’s brand new once more.

Compact, Powerful, and Long-Lasting Handheld Fan with Extra Features
Color: Pink
I took this little handheld fan to a concert in mid June last year and absolutely loved it. It is small, easy to carry, and holds a charge really well. I have probably used it for over 3 hours on both low and high speeds, and it is still going strong on a single charge. I also really like that it doubles as a battery charger and a flashlight, which makes it super convenient to have on hand for different situations. Another great feature is the safety design. The blades automatically stop if anything comes into contact with them, which is appreciated. Overall, this is a great portable fan that I would definitely recommend, especially for concerts, travel, or hot days outside.
