Review title is Easy to Use [SEP] These vacuum spray bottles are very easy to use. They're especially useful for cosmetic products that contain ingredients that start to degrade when exposed to air. They're ideal for toners, hydrating mists and even essences. They pack well and are leak-resistant. This is a great buy.<br /><br />Thanks so much for taking the time to read this review. I hope the information that I've provided makes your decision a little easier.
