LONGWAY 2.7Oz (80ml) Clear Airless Cosmetic Cream Pump Bottle - Travel Size Refillable Dispenser for Foundation, Shampoo & Skincare (Pack of 6) | Perfect for Travel, Gym & Daily Beauty Routine

So before I do a review I like to use the product if possible. I did read sooo many reviews, and some people that were unable to clean the bottle’s properly. Before using I would definitely suggest washing really well, for some reason my items were a bit oily when I received them.They do break down completely! ALL pieces can come apart; that includes the bottom. Just pull and it will pop right off, at that point just make sure you remember the correct placement of the clear plastic piece that goes inside that will later pushup whatever product you put in it. I was able to clean the cylinder and all the pieces very well with soap and water. Then definitely let them dry completely before assembling them back together. You definitely do not want to put any product in a wet container.It worked great for my Facewash, because its not watery or doesn’t have anything in it that could possibly clog the pump. I used it for my leave in conditioner also, its not very thick, so it works perfectly. I also put my Frizz Ease hair cream in one as well, and have no problems with it coming out.I do not think any oils would be good as it might leak, being that its a thin consistency. Although I have not tried it either, so I could be wrong.On a side note, I did read a comment from a prior individual saying that their lids cracked easy. I did notice that when I took my items on their first official flight; hairline or stress cracks (I guess is what the correct term would be) on just the lids, not the actual bottles. They were not huge, but their were a few. With that being said, I don’t think it a big deal that would keep me from buying these bottles again. The quality is far greater than that of the ones you purchase at Target, Walmart, etc. They can be opened and cleaned, the lids are on securely, and the fact you can get all of the product that you put in out. No banging on the bottles or having to place it upside down.When you have it all assembled and place your product in the bottles, make sure you realize you will need to pump it a bit, enough to allow the air inside to be sucked out. A vacuum or suction is created and the bottom clear attachment will eventually rise, pushing your product up.Hopefully this review will help out the next individual that is unsure.
