Siang Pure Formula I vs Formula II Oils: 7 ml and 25 ml Formats
Siang Pure aromatic oils appear in more than one formula, bottle size and bundle count. The product name, packaging colour and volume all matter, so “Siang Pure Oil” alone is not enough to identify the exact listing.
Formula I and Formula II packaging
The active listings distinguish Formula I with red retail boxes and Formula II with white retail boxes. This colour difference is a useful visual check, but always confirm the formula name printed on the product.
The compact 7 ml bundles
Formula I 7 ml and Formula II 7 ml are each supplied as six bottles with individual retail boxes. Each bundle therefore contains 42 ml in total.
The smaller bottles are convenient for separating among bags or users, but the verified listing remains a six-bottle order rather than a single bottle.
The 25 ml listings
Formula I 25 ml is supplied as six bottles with red boxes, for 150 ml total. Formula II 25 ml is supplied as three bottles with white boxes, for 75 ml total.
Because the pack counts differ, compare both bottle volume and number of bottles before ordering. A larger bottle does not automatically mean a larger total bundle.
How to use aromatic oil responsibly
Apply sparingly for external aromatic use and follow the directions on the original packaging. Do not ingest. Avoid the eyes, mouth, broken skin and sensitive areas. Keep the product out of reach of children and stop using it if irritation occurs.
How to choose
- Choose by formula first: Formula I or Formula II.
- Choose 7 ml for the compact six-bottle format.
- Choose 25 ml when a larger individual bottle suits your routine.
- Check pack count: the current 25 ml Formula I and Formula II listings do not contain the same number of bottles.
