    5.0 out of 5 stars DRIES FAST!
    Reviewed in the United States on September 11, 2024
    I got the fluorescent orange "tubocharged" after getting a dip mani I really liked. It is pretty close to the color of a construction zone cone. So VERY vivid.
    I usually only use the quickdry/fastdry Sally Hansen colors as iIam terrible at waiting for my nails to dry. I did this in thin layers (tho even thin ones are mostly opaque) with no base and my first finger was dry to the touch before I was done applying my second! No tackiness or mushy-ness from nails or fingers.
    Ultimately I did 2 layers and it looks pretty opaque. It does seem to be somewhat satin finish, so I added a layer of the fastdry Sally Hansen clear for a shiny topcoat cuz I like my nails to shine. But the satin finish was very pretty too.
    I am also incredibly hard on my nails (can chip dip and gel in minutes of getting it applied). I do home repairs, gardening, engine work, bathing kids and pets, you name it. I am midway thru day 2 with this and no cracks, chips, or peeling yet! I will come back and add more when I've seen how this can withstand my day to day! Crossing my painted fingers that it withstands abuse cuz I LOVE the color and ease of application!
    Update:
    I spent the weekend power washing my house, cleaning rain gutters, weeding, doing dishes, and doing all the housework/childcare. This means I also took quite a few extra scrubby showers! Attaching updated picture of nails! I didn't prep my cuticles in the first one, so A lot of the lost color near the base in the update is just new growth, but you can see that there is some chipping. When I noticed the chipping, I picked all the lifted color off to see what I was still working which, which is still pretty impressive. Honestly, knowing that dry time is pretty non-existent, I'm not even mad that I might have to redo 2-3 nails after a heavy work weekend. Still highly recommend!
    Last update:
    Posting full week later pics! Has withstood multiple sessions of lap swimming along with previously highlighted chores. I also picked the lifted edges before this last set of photos to be sure the fully diminished look was provided. Still recommend!

    5.0 out of 5 stars Love this brand. Long wearing and different. I like the variety. Lights to dark colors.
    Reviewed in the United States on January 8, 2025
    Goes on easy. Nice brush, covers in 2 coats, then top it off with "glass" top coat. Lasts nearly a week even with hands in and out of water. You can also touch it up for chips and cover with the glass coat and it's easily fixed. Buying a color nearly every other week. Downside is, it's shipped from the West Coast so it takes a while to ship. Telling friends how good this is. Maybe with more customers, they will stick some on the East Coast.

    I love this polish! 2nd one I've purchased and could not be happier. Quality is really good. This particular color is so awesome. Kind of a slate blue, hint of gray and some shimmer. Perfect to winter! Will likely go broke purchasing more colors! Haha

    Reviewed in the United States on January 27, 2025
    this polish is so pretty and so far (????????) seems to be pretty durable. i’ve been wearing it for 3 days now with no issues so far. my main complaint is that for some reason i couldn’t really get the pattern to show up with the magnet, so it kind of just looks like normal glitter polish. the glitter also kind of pooled in places so it looked a bit messy. it’s still gorgeous though and i would absolutely recommend

    Reviewed in the United States on January 15, 2025
    Not only was this my first ILNP polish experience, but my first major holographic polish as well. It meets EVERY expectation, and despite my mediocre nail skills, makes my nails look salon-done every time! For me, the original Mega was the best choice - I get the best of linear and scattered holo without the particles being too big, and it looks great on my short nails! The wear is also excellent - I've had them last a week without any chipping or wear besides the some minor weardown at the tips (which is hardly noticeable), and this can probably be lengthened with better base/top coat coverage too. The holo can disappear without direct light, but I'm left with a lovely silver color until the light returns.
    It's beginner-friendly and truly magical-looking without being overly garish. I'm slowly trying their other holos as well, and Chai Latte is also a stunner! ILNP certainly knows their holos! :D

    5.0 out of 5 stars Amazing!
    Reviewed in the United States on January 20, 2025
    When I first bought this, I thought, "This is expensive," but as soon as I saw how beautiful my nails looked after using it, I realized it was worth it! Even my co-worker was happy—we both used it at the same time. He usually wears dark colors, and we have different hand shapes, skin tones, and textures, but it was amazing how great we both looked after it dried! I will definitely get more!

    5.0 out of 5 stars Beautiful Nail Polish, Easy to Use
    Reviewed in the United States on January 3, 2025
    First thing I'm not an avid nail polish wearer but this brand has got me to repurchase twice in last two weeks. I first ordered bitten to see what the quality was like or if I'd even like it, was pleasantly surprised by the quality and ease I had using this. Polish stayed on for about a week without chipping, which is something I've never encountered even with pricey nail polishes, only gel polish has been able to hold up on my nails. Just bought fairy floss and ball drop and both are beautiful ❤️. Excited to keep finding new colors to add to my collection. This brand is top tier in my opinion.

    5.0 out of 5 stars I mean... look at that shine!!!
    Reviewed in the United States on December 20, 2024
    I was originally bummed because the package seem a bit late; however, when this beauty arrived I was amazed. Totally worth the wait!
    The picture has no flash on, no filter. I applied two (2) layers of product, not overly saturated, and this was the result. Amazing coverage and pigment... I mean... look at that shine. I have no top coat yet on this picture. You can see the sparkle. The nail polish dries fast and flawless. This was my first ILNP buy and will DEFINETELY get more!!!! Obssessed!!!

    Edited: Second picture is Poison ILNP Magnetic nail polish. I mean, depending the lighting is the color that shows. Goes from a copper brown to poison red. Like... again... obssessed.
