Review on Refillable Amber Glass Bottles with Stainless Steel Roller - Preserving Quality and Ease of Application by Jamie Prezant

These bottles were perfect for my purpose of giving samples to my classmates to showcase essential oils. They were very successful and allowed me to provide samples for 48 people at little cost. I had no issues with leakage and all inserts fit perfectly and worked great. I used a special tool designed to install and remove these inserts and dropper inserts to make sure each one is fully depressed and I haven't had any issues with them. Nothing broke, and I've actually dropped a few of these on the floor with no damage, so they're pretty solid. One thing I should note though: I didn't use them all, and I didn't count the extra inserts and caps to make sure they all fit.
