With Forever Bottles you can be sure you are getting the best quality, guarantee and service on the market! Those are not just words. We went through some years of correcting every little point and we are now proud to let you know that you are getting the strongest and shiniest glass in the market. It's quite visible. We have the darkest amber and cobalt blue on the market so that the UV light protection is keeping your valuable oils in good condition. We tried many roller balls and we believe we now have the optimum kind that is not going to leak, fall or get stuck and we are one of the only companies with a glass roller. Glass is just better on the skin than metal and is BPA free. Another point that took a whole evolution was the lids. Good lids are important because they push the roller ball down and seal the bottle from leaking when on the go. Notice the quality of the lids, they screw all the way and they are so beautiful! We even invested in the package. You will notice the beauty of the glossy dark blue and the silver logo, the bottles are protected with a foam so that they arrive to you in a perfect condition. One of our main advantages is the quality control! Every bottle, roller and lid is checked before it goes to Store! And if from some reason we missed something, no worries, customer service is above and beyond. We will make you happy! As to the eBook, it's a long story but you will be able to use it both for blends and as a fascinating collection of data about some of the important essential oils that we use. The data will help you come up with your own ideas too. Many of our customers are professional aromatherapists. You deserve the same quality of the professionals.
