Travel toiletries and home toiletries in these bottles eliminate the fingers in the jars problem. Precise amount dispensed and no bottle leaks from expanding air. I have these in two different sizes and they are lovely for my skincare. I have one very thick product that is tedious to fill the bottle but will dispense with sputters. Not the bottle's fault, just that product.You should try these!These did exactly what they were advertised to do. They were easy to fill and easy to pump and didn't leak. I couldn't ask for more.Every pump worked (and still working) compare to the competitors' bottles.Extremely easy to fill. Great for travel: you don't have to carry big bottles of different sizes of products with you. These bottles fit into a regular sized cosmetic bag, all uniformed, easy to clean if necessary: perfection!These cute airless pumps are great for serums! One pump and you have all the product you need for a one time application.First of all, these are incredibly convenient to use once the product is in the bottle. The reason these don't get 5 stars is that filling them can be a PAIN. Size of the bottle opening is rather small so if the original container has a wider mouth and the substance is thicker, it can take a WHILE to fill. Took me 25 minutes to fill 2 of these with face creams that came in jars and I lost a lot of product in the transfer. I used a product spatula and it was still a very messy process. I don't know that a tiny funnel would have helped in this case because the creams were fairly thick, but I would recommend getting one separately for other, thinner products like lotion or serum. Or go with a set that includes the funnel.Easy to use, great lookingLove these airless jars! Although the opening is very small (it’s hard to get product in, even with a funnel) I think it’s worth it! I feel like I get so much more product and it’s nice to have all my different creams/lotions in the same looking jar. Makes it much easier to store & organize.Works perfect and cleans relatively easy, just wish it held more product. The hard plastic cap may break if dropped too hard.Great quality. Sleek and a comfortable size. Will be ordering more in future.
