Transferring old paint to new bottles

I've had a problem with my older paints drying out, and figured it was finally time to transfer them over to some new dropper style bottles. I'm still researching what I can use as agitators. I think I'll will purchase some ceramic beans used for blind baking

You can get these dropper bottles from container and packaging supply. I ordered black PP 15-415 dropper tip cap (item L506BL), natural-colored PP 15 mm controlled dropper tip (item L502C), and 1/2 oz natural-colored LDPE boston round bottle with 15-415 neck finish (item B443).
