What do you need for acrylic nails?

To apply acrylic nails you need...

several nail files and buffers

a cuticle pusher

nail clippers

a tip cutter

nail tips and tip glue

acrylic powder - at least a pink, and probably also colored acrylic for the tips (this has a shelf life)

acrylic monomer (this has a shelf life)

a brush

primer (this ALSO has a shelf life!)

top coat. If you use gel top coat you need a lamp to cure it.

To fill them you also need acrylic nail nippers

IME it would cost you more to set up for doing your own acrylics than it does just to go get them done.
