EZ Well KF94 Quarantine Mask is a quality product approved by the Korean Ministry of Food and Drug Safety. In addition to this, has both FDA and CE certified

Respiratory protection from harmful particulate matter such as yellow dust, fine dust, and infectious sources

1. The three-dimensional quadruple structure certified by the Korean Ministry of Food and Drug Safety securely blocks the outside (4 Layer using a melt-blown filter)
2. A fine dust mask that is comfortable to breathe because it does not touch your mouth! Excellent breathability.
3. It adheres smoothly along the face line and prevents fogging with the nose wireframe and ear wireframe.
4. It has an Excellent Mark from DermaTest in German which did not lead to toxic-irritative intolerance reactions in patch testing carried out in accordance with international guidelines

L-Lysine Sulfate 65%/70%, CAS No.60343-69-3, a brown granule, feed grade. L-Lysine is a necessary building block for all protein in the body. As a nutrition supplements, L-Lysine Sulfate used in food production, beverage, pharmaceutical, agriculture/animal feed. L-Lysine Sulphate 65%, equal to 65% lysine HCl, could provide 51% free lysine in the feed. It has already been proven that L-Lysine Sulphate has almost the same feed effects L-Lysine HCl.

As an experienced L-Lysine Sulfate manufacturer and supplier, we has been supplying and exporting L-Lysine Sulfate for almost 10 years, please be assured to buy from us. Any inquiries about price and the market trend please feel free to contact us, we will reply you within 1 working day.
