Class Parfum · Buyer Education
Fragrance guides for buyers, refill users and resellers.
Clear, practical guidance on fragrance concentration, bottle sizes, refill and sampling workflows, wholesale sourcing and factory-supported projects.
Start with the decision
Choose the information you need.
Choose the product type first. Class Parfum 20% Eau de Parfum refills are finished fragrances, ready to wear. Our pure fragrance oils are perfume concentrates for formulation and must not be used undiluted. For resale, large-format supply or custom projects, start with our wholesale options.

What does 20% fragrance concentration mean?
Learn what a concentration percentage can tell you—and why formula, materials, application, skin and environment still affect the experience.
Perfume refill sizes: 100ml vs 500ml vs 1000ml
Understand when 100ml, 500ml or 1000ml may fit personal use, refill routines, sampling, boutique testing or established reseller demand.
Plan a wholesale project
Prepare scent direction, quantity, destination and packaging requirements before requesting a reseller, bulk or custom-fragrance quote.
Size planning
100ml, 500ml or 1000ml?
Use the smallest format that supports your real demand. Larger sizes can improve workflow efficiency, but they also place more inventory, cash and storage capacity behind one scent direction.
| Size | Often best for | Primary consideration |
|---|---|---|
| 100ml | Personal wear, compatible atomizer refills, product testing and limited samples | Flexible entry point with lower inventory commitment |
| 500ml | Repeat refill use, established sampling and small reseller testing | Requires clean handling and validated demand |
| 1000ml | Higher-volume sampling, repeat boutique programs and experienced resellers | More inventory concentrated in one scent direction |
Responsible buying
Concentration is one specification—not a universal promise.
A 20% fragrance concentration describes the proportion of aromatic fragrance material in the finished formula. It does not guarantee the same projection or number of wear hours for every scent and customer. Formula structure, application, skin, climate and storage all influence performance.
For personal buyers
For a finished fragrance, start with scent direction and a manageable refill size. Check the product page for current size and stock availability. See how perfume refills work before ordering.
For sampling programs
Use clean, compatible transfer equipment and containers. Label transferred product clearly and keep source records where applicable.
For wholesale buyers
Validate demand before scaling. Include quantity, destination and packaging requirements when requesting a quote.
