Please read the self-introduction. Stainless Steel 304 2-Loop Post Earrings Size: 37 x 15mm (Pin: 0.8mm) *Includes backings! Price for 4 pieces (2 pairs). Inventory: ○ ★ Single pair: ¥200 ................................................ ─︎─︎About Stainless Steel Products─︎─︎ We often get asked, "Is it surgical stainless steel?" However, the main materials of the parts often seen in terms of quality are: ・Stainless Steel 304 (SUS304) ・Stainless Steel 316 (SUS316) ・Stainless Steel 316L (SUS316L) These three types are essentially the same (..). The only difference is the percentage of nickel (Ni) contained, which decreases as you go down the list. SUS304 contains 8% Ni, and SUS316 contains 12% Ni. SUS316L is stainless steel with added molybdenum (Mo) to improve corrosion resistance and pitting resistance. Some shops label SUS304 as "allergy-free" or "surgical stainless steel," but since allergic reactions vary from person to person, we do not use such labels. Please be aware of this. By the way, stainless steel 201 (SUS201) has a few percent less chromium (Cr) and nickel (Ni) than the above three types, so its corrosion resistance is slightly inferior. However, stainless steel products, regardless of type, last longer than low-priced alloy products ✧︎*。 For your reference... ..................................................... ✩︎≫≫About combined purchases of regular products ¥170 off for the second item ¥340 off for the third item ¥510 off for the fourth item and so on, with a ¥170 discount for each additional item. *Single items are not eligible.
