more stirred than shaken [SEP] i like this however i do not think it shakes fast enough or enough i have some nail polishes with quite a bit of glitter and the glitter did not move the bottle was on its side for a while and the glitter had floated to one side i used this shaker and had it there for what seemed like forever and maybe a few pieces of glitter movedplease let me know if someone recommends something better i love nail polish and have too many bottles i think it is good to shake them up once in a while and would rather not manually do itthank you in advance
