I like the size of the dropper that is included as it allows you to get every bit of your product without letting any go to waste. I used my bottles to fill with some of my candle oils I’ve been crafting and this makes candle preparation a whole lot easier. The bottles are sturdy as I tipped one over by accident and it didn’t break or crack. You will need to get a funnel as one is not included to make filling each bottle easy and mess free. I highly recommend this to anyone crafting their own oils at home!
