01Market Opportunities
Kits account for 30% of the sample SKUs and contribute 51.7% of sales
Among 40 sample products from the U.S. site over the last 7 days, 12 beginner kits contributed more than half of total sales.
Average sales per kit SKU are about $10,333, 3.3 times that of basic single boxes. You can first validate demand for beginner kits, then track sales and ad spend ratio by SKU during reviews.
02Competitor Comparison
At the same $19.90 price, what more can you solve?
The sample competitors include complete accessories, but lack guidance on eye shape and length. Add a matching guide image first so beginners can choose more easily and get started faster.
| Product | Price | Sales volume | Configuration and gaps |
|---|---|---|---|
| Basic single box | $9.90 | 2,400 | More pieces, tools sold separately |
| Beginner kit | $19.90 | 1,600 | Complete accessories, but lacks eye-shape guidance |
| Premium gift box | $29.90 | 600 | Elegant packaging, high trial cost |
The chart shows totals by combination, while the table shows individual product examples. When comparing prices, include discounts, shipping, and the total cost of completing the tool set; the cost of producing the matching guide image is not included in this example.
03Market Entry Check
Before listing, also check the entry requirements for kits that include glue
Product classification and documentation
Check the U.S. site’s category classification and documentation requirements for false eyelashes and glue. Different components of the kit may need to be reviewed separately.
Labeling and claim substantiation
Check the glue ingredient list and packaging labels. Any efficacy claims should be supported by documentation provided by the supplier.
Logistics channel restrictions
Confirm whether kits containing glue can use the selected first-leg shipping and U.S. warehouse fulfillment channels, as acceptance conditions for liquids or chemicals vary by channel.
Consistency between samples and bulk goods
Confirm that the glue and packaging versions are consistent. If the formula or label changes, a recheck is required.
04Cost and Profit Calculation
At a $19.90 net received price, calculate every cost clearly
The following estimates are based on a single order, with fee rates calculated on the net received amount. Ad and creator orders are calculated separately, without double-counting customer acquisition costs.
- Product cost
- $3.20
- First-leg shipping + warehouse fulfillment
- $4.10
- Platform/payment fees
- 8%
- After-sales loss reserve
- 5%
Set aside a separate budget for inventory purchase, content production, fixed operating costs, and taxes. Actual profit will vary with fulfillment costs, refunds, and customer acquisition costs.
Same price, different profit margins
- Ad-only order
- $3.51 / order
- Customer acquisition cost $6.50 · Contribution margin about 17.65%
- Creator-only order
- $7.03 / order
- 12% commission + $0.60 sample allocation · Contribution margin about 35.30%
In this example, the break-even ad customer acquisition cost is about $10.01/order, corresponding to a ROAS of about 1.99 (GMV ÷ ad spend). At this point, the variable cost per order is just covered.
Expand to view the calculation formulas
Ad order: 19.90 × (1 − 8% − 5%) − 3.20 − 4.10 − 6.50 = $3.513/order
Creator order: 19.90 × (1 − 8% − 5% − 12%) − 3.20 − 4.10 − 0.60 = $7.025/order
05Creator and Content Direction
2 creators, two types of creatives for comparison
At the same selling price, have each creator produce two types of creatives and compare which one drives more conversions. Use first-round results as directional reference only.
Application tutorial
Fully demonstrate how beginners apply them, and show how to adjust if they are applied unevenly. Set aside a separate budget for creative production costs.
Makeup effect comparison
Keep lighting consistent and label different lengths and eye shapes. Judge by conversion performance, not just views.
Before sending samples, agree on the ad usage scope and authorization period for the creatives, and keep the product links and ad delivery records for each piece of content.
06First Trial Sale Plan
Set limits first, then decide whether to add more
- 01
Inventory ≤50 sets, including samples
If the supplier can handle small orders, reduce inventory pressure first. Separately include the per-unit shipping difference caused by small batches in the test-selling cost.
- 02
Ads ≤$300, review after every $100
Once attribution data for transactions is complete, invest the next amount only if contribution profit remains after deducting the after-sales reserve. Set aside a separate budget for inventory purchase and production costs.
- 03
Customer acquisition cost ≥$10.01, or no sales in this round
Pause additional ad spend. Recalculate after refund data comes in, then decide whether to adjust creatives, pricing, or restocking.
