I’m really loving these roller bottles! I think I will be getting more in the future as they would make lovely gifts. I was first attracted to them because of the color and the refillable roller part. I had no idea they would be such good quality! These come in a pack of two and are very easy to pop the roller into it and get it back out but not so loose that you would need to worry about it falling apart. (there’s a screw on top too) I much prefer to roll my scents on and my partner and I have been planning to make bug repellant from our citronella plants so these are perfect! I cannot wait to get my oil made up and stock up for summer! I got this item at discount, all reviews and opinions are all my own. Find yours here !
