Ex Input:
The glasses were great! The ice molds were a let down. Only one of them held water and the other is essentially useless because it doesn't hold the seal and water seeps out only making 1/2 and ice ball. Pretty disappointed

Ex Output:

Ex Input:
These notepads are difficult to write on with a Fisher Space Pen. It does work, but the writing is rather splotchy. Works great with gel ink (but may smear), and is alright with regular ballpoints. It repels water on the surface, but the edges allow water to seep in, so underwater writing may not be a good idea.

Ex Output:
3

Ex Input:
I love this polish but this is a complete rip off. It states that it is for 6 cans but you only receive one. Price $39.00. They do not except returns on the item so your stuck with it. Wish I had never ordered. Don't be duped like I was.
