nail brush for DIY gel

i’m in a crunch and wanting to know if i can find a nail brush that mimics a bottled brush. i’m wanting to make my own pink jelly color with this pink i have. i tried looking but not super familiar with nail brushes other than for nail art, i tried looking online but everything is for delivery or else i would go to amazon but i need it tonight.

would an acrylic brush be similar, thickness wise?
