> 3 dayThe size of these hooks was totally wrong in the description. Here are pictures with a ruler which shows how many inches they are ,Hight and Width. The manufacturers should be doing this. They have no clue. It seems they measured the box that they came in ,not the actual item.

> 3 dayAmazing little hooks! I bought them to be able to hang stuff in my locker and my kids artwork on my locker. They don’t even move if I tug on them. I need both hands to get them loose. Definitely a 2 thumbs up purchase.

Neosmuk’s products are mainly composed of steel and (ND2-FE14-B). With the help of our state-of-the-art powder metallurgy technologies. So far, a maximum energy product of 414KJ/m3(52MGOe) has been produced, and high coercivity high energy product like NS-50UH is also available.
Our magnets achieved the world’s highest levels of remanence Br, intrinsic coercive force Hcj, energy product (BH)max, and temperature stability. A full range of magnetic characteristics provides the most optimal solution to magnet selection, enabling radical down-sizing, lightweight, and super powerful magnetic devices.
An ‘into market’ service system has been built so as to respond quickly to concerns from our customers and iron out the difficulties of technical issues. Years of experience in the calculation and design of magnets using the finite element method decisively shorten the development period and increase the satisfaction of our customers.
We have done critical actions for establishing a sustainable and stable supply chain for low-cost high-power products by the way of reducing light earth elements and avoiding using Tb(terbium), Dy(dysprosium), and other heavy earth elements with high market fluctuation risks, and initiating a new magnetic property series equivalent to those of the world’s highest level high-power materials
As a manufacturer having plentiful R&D ability on magnetic circuit designs as well as outstanding quality and high-performance magnets, we energetically support the application and optimization of products using magnets
Note：Whether magnetic hooks can hold 0lb, few pounds,many pounds, your steel is decisive!
1. A thicker Steel:
Thin steel means saturation of flux in the magnetic circuit. Excess magnetic flux is wasted in the air and can"t be utilized.
2. Thinner painting/no spacer
Thick painting will give rise to a great leakage of flux,only a small portion of flux from magnetic hooks can be utilized to provide the attractive force.The thicker the painting, the worse the magnetic force!
3. Please be reasonable when sticking the magnetic hooks to a thin steel with thick and smooth painting at sideways, like Refrigerator,Filing cabinet...etc,because most flux is wasted in air !
Warning and Precaution!
- It is extremely dangerous to bring a magnet close to a person possessing electronic equipment such as a pacemaker or other types of electronic medical equipment. It may impair normal operations of the equipment and lead to a fatal accident.
- Keep magnets always from magnetic recording media such as floppy disks, magnetic digital cards, magnetic tapes, prepaid card. If it is placed near to a magnetic recording medium, recorded information may be destroyed.
- Do not store magnets in places where they are exposed to rain or dust or under conditions in which moisture condensation occurs; Don’t expose to fire or places with high temperature,surface conditions, physical properties, or magnetic properties may change if stored under such circumstances
