Thanks, will check them outUnfortunately they are battery powered but I have a tiny hand blender meant for acrylic paints. The tip fits into most of my 30ml bottles and stirs up without excess air bubbles. I'm just too lazy to use it usually, I give things a shake and throw them in the cupboard. https://www.amazon.com/gp/aw/d/B000...aint+mixer&dpPl=1&dpID=21Ws4-oWJiL&ref=plSrch
