Review on Refillable Containers Aromatherapy Essential Fragrance Travel Accessories by Tina Hall

The caps are secure and will not leak. They are VERY difficult to open meaning the buyer may struggle with the lid. You have to slowly rock it back and forth by gently pulling (painful on fingers and takes a long time before it spills). I have to warn customers that in case of spills they should open with a handkerchief or something. Again. Great lid with no leaks, but as they are very difficult to open and can cause pain, frustration or product loss (especially if opened more than once), gifting them as gifts is useless to me.
