Nice curtain for the price
Color: White, Size: 72"W x 72"L (Pack of 1), Color: White, Size: 72"W x 72"L (Pack of 1)
Very nice curtain. Feels durable and I love the waffle texture look. I bought it to replace the kiddish one I had in there for staging purposes. Fits great, no odor when opened the packaging. Easy to hang and good value for money.

holds up, cleans well, looks good. what else do you want
Color: White, Size: 72"W x 84"L (Pack of 1)
I almost never write reviews, but for a random brand amazon product, this is high quality. I have a very tall shower so was struggling to find anything locally and ended up buying this. It looks nice, feels thick and sturdy but isn't super heavy so I don't have to worry about it pulling the tension rod down. It's opaque enough to not see through but lets enough light in. All that is kinda whatever, it's the functionality I was looking for but nothing to write home about. The thing is, my plastic inner curtain liner is way too short, maybe by like 6 inches. After a year of use, this left an area exposed to water, shower products etc. and it got pretty grimey. I was thinking I'd need to replace it but decided to try and bleach the bejeezus out of it and then let it sit in hot soapy dr bronners water. Now it's basically good as new. Idk if you could throw it in a washer, I personally wouldn't but this worked great. I respect a cheap product that does it's job, looks good, and cleans easily. You do need an inner liner though unless you're ready to bleach it frequently. Or you don't care about stains at all, that's your prerogative.
