Hi just a quick question, I received my pioneer pack today. I have inserted the ashawaghanda vial inside and tried three sprays. My question is, are you able to chop and change the vials and then pop different ones in? I’m eager to try the valerian one this evening before bedtime. Any help greatly appreciated. Such a lovely device and packaging. It’s been such a long time to receive the pioneer pack as I think it was like a year ago but it’s finally here. Very please.
