This is my all time favorite bit ^ I've had it for two years now, and it's a staple for my acrylic services. I use it for shaping, taking down length, removing old polish, etc, and I highly highly recommend it. I also have this set (https://www.amazon.com/dp/B07XT3RFKN?ref=ppx_pop_mob_ap_share), but realistically, I only use the small cuticle bit. When I do acrylic sets and fills I really only use those two bits, and haven't needed any others
Other than that, get yourself a really good acrylic brush, if it runs about $30 USD, you're in good territory. Amazon also has good handheld e-files if you need something good but inexpensive. I personally use this one (https://www.amazon.com/dp/B086X69K8Y?ref=ppx_pop_mob_ap_share) - it still needs to be plugged in, but it's really good for the price.
My Japonesque toenail and fingernail clippers have lasted me years, and are the only ones I use on clients. And I always recommend getting yourself a really small flat brush for polish clean up and French tips
Hope this helps! ❤️
