How to label a 30ml perfume bottle
For a 30ml bottle, preserve the manufacturer's identity and add personal notes separately where possible. A collection label should make the bottle easier to find without hiding product information.
A HUME Fragrance buying guide

Keep the exact version
Similar bottle designs can contain different concentrations or fragrances. Use the complete supplied name.
Link a journal entry
Record opening date or preference notes in a separate inventory rather than overcrowding the bottle.
Avoid altering the package
Do not remove labels, force closures or add adhesives without considering the container's materials and instructions.
Try this before you buy
Create a collection entry that identifies the compact bottle while leaving its supplied label intact.
