Review title is How to open? [SEP] Looking at the design of the case this is in, it looks like the smaller part of the top should open.  If it is suppose to open, I can't figure it out.  So, I just unscrewed the entire top off to use it.  Not really a big issue.<br />The foundation itself is waterproof.  Does last all day with no problem.<br />It's a nice smooth foundation.  Easy to apply with the sponge that comes with this.<br />It does cover up some of the skin flaws.<br />It's an okay foundation for a decent price.  Kept my skin soft all day.<br />Was easy enough to wash off at the end of the day.  I would buy again.
