Dekang here as well. Their older style bottle was white cap with tamper resistant ring (like soda pop bottles in the U.S. have). Their new style bottles are child resistant caps in varying colors (ones theyve sent to me are white, two different shades of orange, blue, and green - they'll put different colors on different liquid strengths)
The change from white with tamper-resistant ring to childproof color cap happened around June. Some vendors (including myself) have a mix of cap style in their inventory. Some of us (including myself) also still have 36mg from Dekang. There's a few reasons some of us will have the older style cap and/or still have 36mg. I.e.: I have some 36mg w/ old style caps that customs held for a few months before finally letting me have them.
