Installation Manual

SIZE GUIDE

Our signature product

Before you can interface with your Glitch Nail set, you must properly calibrate your hardware. Install the wrong size, and your fingertips will look like an oversized CRT monitor on a tiny desk. Do not let that happen.

Step by step

STEP 1: HARDWARE REQUIRED

  • A flexible measuring tape
  • A strip of paper and a ruler
  • A working pair of eyes
  • Place the measuring tape or paper strip across the widest part of your natural nail bed (the middle). Do not measure the skin. Do not measure the tip of your finger. Measure the flat, fleshy surface where the press-on will actually sit.

Pro-Tip for Thumbs: They're always bigger than you think. Don't guestimate. Measure.

STEP 4: THE DIAGNOSTIC TEST (The Dry Run)

Beforeyou peel any adhesive tabs, take the physical Glitch Nail set out of the tray and place them gently over your bare nails.

  • Does it cover the entire nail bed without pinching your skin? Correct size.
  • Does it look like a hubcap on a skateboard? Size down.
  • Does your natural nail look like it's wearing a crop-top? Size up.

⚠️ WARNING:
If you order blindly and guess your size, the software will reject the installation. We offer exchanges (via our Swap File protocol), but it's faster if you just measure the first time.

Still confused?
Send a photo of your hand holding a ruler to hello@glitchnail.com with the subject line "SCAN FAILURE." We'll personally diagnose your biometrics within 24 hours.

Frequently asked questions

How long do these actually last?

7–10 days with proper prep. If you apply them like a feral animal, maybe 3 hours.
Can I use UV gel or LED topcoat on these?

Absolutely not. Heat from a UV lamp will warp them faster than a melted plastic water bottle in a heatwave.
How do I take them off without destroying my natural nails?

Soak a cotton ball in pure acetone, place it on the nail, wrap it in foil, and wait 10–15 minutes. The glue will dissolve. Gently scrape it off. Wash. Moisturize. Breathe.
 Can I reuse them?

Yes. After removal, peel off the old sticky tab or gently scrape off the dried glue. Store them in the cardboard tray they came in. Do not store them in your pocket. Do not store them in a humid bathroom.
What if I lose a nail?

We include 2 extras of every size in your set (24 nails total). You have backups.
 Do these damage my natural nails?

Only if you rip them off aggressively. Follow removal instructions and you'll be fine.
