Sizing Chart
Nickel Smart Belt Sizing Guide - If you have questions, please call us! 704-947-1917
This sizing chart will work on Nickel Zero® belts too.
Most of our belts are sized from the buckle fold to the middle hole. A 34” belt will have a center hole at 34” and two holes on either side of the center spaced 1” apart each. A 34” belt can be worn as small as 32” and as big as 36”.
  • There are several options to determine your ideal belt size.
  • The ideal way is to measure your waist through your belt loops. This measurement is the size of belt you should purchase (i.e. if you have a 34” measurement, order a 34” belt).
  • An alternative option is to measure your old belt from the buckle fold to the hole you use. If your belt measures 34” from buckle fold to the hole you use most; then order a 34” belt. This will give you a belt with 2 holes either side of the hole you use most.

Nickel Alert® is a fast, effective way to test any metal object for nickel so that your skin doesn’t have to. If you have a nickel allergy, you know that even a small exposure can cause a big problem. Don’t take the chance of getting stuck with a nickel rash; use Nickel Alert to test your jewelry, watches, household objects, and more.

Let Nickel Alert test for nickel in your jewelry - NOT your skin! Have a lot of items to test? Try this economical two pack - over 400 tests! The convenient two pack lets you keep one bottle at home and take one with you when you shop for new jewelry. Yes, test the "nickel free" jewelry to verify it really is nickel free!

Nickel Alert is also available as a Single Bottle.

Use Nickel Alert in a well-ventilated area.


Nickel Alert is an extra sensitive dmg spot test that can detect nickel at a level as low as 10 ppm (parts/million) - a threshold below which only individuals with the most pronounced sensitivity to nickel would experience a reaction.

There is no cure for nickel allergy, just avoidance – Nickel Alert detects nickel so you can avoid it. It's safe to use on even the finest of jewelry.

One 0.5 ounce bottle is good for 200+ positive tests! It takes about 30 seconds to use, so if you aren’t sure what’s causing that itchy allergy rash, it won’t take long to figure it out!
