## Description

REALTH Square Magnets 12Pack Neodymium Magnetic Cube 0.39 Inch, Rare Earth Magnets for Research Industrial Purposes Educational: desertcart.com: Industrial & Scientific

Review: Neodymium Necessity - I bought these magnets for an unconventional reason - they were the perfect size to fit down the 14mm down-stem in my bong. When I found out that purpose-built magnetic scrubbers start at around $30, I decided to make my own. I had hot glued a scrubbing pad to one of these, and it worked even better than I had hoped. As for the rest of them, I will be using them to create some fridge magnets with some thrift store finds. The magnets are super strong, and I’m very happy with my purchase.
Review: Awesome customer service! - The first set i recieved were quite literally destroyed, as you know this type of magnet is very brittle. That being said I contacted the company and actually had a replacement pair in hand before I could ship the broken ones back. Absolutely awesome customer service. Replacements were perfect and worked exactly where I needed. This seller is absolutely my goto for anything magnetic going forward.

## Features

- Composition: Neodymium magnets are composed of neodymium (Nd), iron (Fe), and boron (B). The combination of these elements results in a crystalline structure that contributes to the magnets' high magnetic properties.However, this crystalline structure also makes the material inherently brittle.
- Size: Various sizes can satisfy your various choices. We provide the perfect size for a variety of applications.
- Brittleness: The brittleness of neodymium magnets, is primarily attributed to their composition and crystalline structure. Neodymium magnets can easily chip or break, especially if subjected to impacts. Magnets can attract to each other with great force, so avoid dropping them or subjecting them to impacts. These magnets have triple layer coated with Nickel+Copper+Nickel to provide a shiny and durable protection.
- Applications: Due to their magnetic fields, neodymium magnets find applications in various industries. Common uses for research, industrial, and educational purposes.
- Service: Search for Realth on desertcart for more sizes, shapes, functions, and other unique magnets.
