WHY THIS MATTERS
The Sample is the Most Important Step in Your Entire Project
The sample is the only moment in your project where you can physically evaluate the formula, feel the texture, smell the fragrance, and check the packaging before committing to bulk production. Most quality problems — and most costly mistakes — happen when buyers skip or rush the sample stage.
What a good sample confirms
- Formula texture matches your brief exactly
- Scent direction aligns with your brand
- Skin feel and absorption meet your claim
- Packaging integrity — no leaks, no deformation
- Label accuracy — INCI list, batch code, net weight
- pH and stability within specification
What we do differently
- Unlimited revisions — we iterate until you approve
- Detailed revision guidance — we don’t guess, we ask specific questions
- Separate packaging samples if needed — compare 2–3 options
- COA accompanies every sample shipment
- Revision tracking — we document every change clearly
- Bulk production only begins after written approval
The cost of skipping it
- Bulk production locked to wrong formula
- Texture or scent mismatch discovered after 5,000 units produced
- Packaging incompatibility causing leaks or deformation at scale
- Label compliance errors discovered at customs
- Review damage from first customer batch complaints
- Re-sampling + re-production cost: USD 3,000–15,000+

How Revisions Work — And Why Ours Are Better
Receive Your Sample

Evaluate Using Scorecard
Assess texture, scent, skin feel, colour, packaging, fill weight, pH, and performance. Write specific feedback.
Submit Revision Brief
Email or WhatsApp your revision requests. Specific beats vague: ‘increase thickness 20%’ beats ‘make it thicker’.

Revised sample ready in 5–10 working days and dispatched via DHL. Repeat steps 2–5 until perfect.
Written Approval
You send written approval. We lock the formula to your brand. Bulk quote issued. Production begins on deposit.
OUR COMMITMENT
“We Do Not Move to Bulk Until You Approve In Writing.”
This is not a policy we enforce when convenient. It is the only way we operate. Your written approval is required before a single gram of bulk product is produced.
