A cushion refill fits a compact only when the physical cartridge and case are compatible. Brand, product line, cartridge geometry and any manufacturer compatibility statement matter more than a shared gram weight. Two refills can both contain 15 g and still use different diameters, locking tabs, hinges, mesh/sponge systems or case depths.
Quick answer
Match the refill to the exact brand and line first. Then confirm the compact/refill family, cartridge shape or product code, dimensions if the manufacturer publishes them, and the shade system. Gram weight is a quantity measure, not a fit specification. If the brand sells separate 8 g “Pocket” and 16 g standard refills for related cushion names, treat those as different hardware families unless the brand explicitly says they interchange.
The compatibility checklist
| Check | What to verify | Why it matters |
|---|---|---|
| Brand | Exact manufacturer, not a similar-looking compact. | Refill systems are not standardized across K-beauty brands. |
| Line | Exact product family: Glow, Matte, Pocket, Mesh, Foundation Pact, etc. | One brand can use several incompatible case systems. |
| Compact / cartridge | Whether the refill is sold for that exact compact or shares an explicit cartridge code. | The refill must physically lock into the case and dispense correctly. |
| Dimensions | Diameter, height, tab geometry or cartridge measurements when the brand publishes them. | Physical dimensions are stronger fit evidence than product weight. |
| Shade system | Shade names/numbers available in that refill line. | Hardware compatibility does not guarantee the same shade range or undertone. |
| Gram weight | 8 g, 11 g, 13 g, 15 g, 16 g, etc. | Useful for quantity/value, but matching weight alone does not prove compatibility. |
| Case fit | Explicit manufacturer statement, matching line SKU, or verified cartridge fit. | Prevents buying a refill that cannot snap into the compact. |
Why the same weight does not prove compatibility
Weight describes how much product is inside the cartridge. It does not tell you the cartridge's outer diameter, height, locking tabs, mesh frame, sponge platform or hinge clearance. Two brands can sell 15 g cushions with completely different refill hardware. Even one brand can run multiple 15 g families.
Use gram weight to compare how much foundation or sunscreen you receive, not as a hardware specification. If a retailer says “15 g refill” without naming the compatible compact line, treat compatibility as unverified.
A current example: JAVIN DE SEOUL Pocket vs full-size refills
The connected ProtoClinical catalog currently contains separate JAVIN DE SEOUL listings for Wink Cushion Glow Pocket 8 g, Wink Cushion Glow Pocket 8 g Refill, Wink Cushion Glow 16 g and Wink Cushion Glow 16 g Refill. The brand's own site likewise lists the Pocket 8 g refill and the standard 16 g refill as separate products.
| Line | Full compact listing | Matching refill listing | What we can conclude |
|---|---|---|---|
| Wink Cushion Glow Pocket | 8 g | 8 g Pocket Refill | Brand and line naming directly pair these products. |
| Wink Cushion Glow | 16 g | 16 g Refill | Brand and line naming directly pair these products. |
| Wink Cushion Matte Pocket | 8 g | 8 g Pocket Refill | Same Pocket hardware family is implied by exact line/refill naming. |
| Wink Cushion Glow Pocket 8 g vs Glow 16 g | Related naming | Different dedicated refill products | Do not assume cross-fit. The official pages do not provide a cross-compatibility statement. |
The Pocket and full-size Glow lines also overlap in shade numbers such as 19, 20, 21, 22 and 23. That does not make their cartridges interchangeable. Shade-system overlap and physical fit are separate questions.
What if dimensions are not published?
Do not invent them. If the manufacturer does not publish cartridge diameter or fit dimensions, use the strongest evidence that is actually available: an explicit “refill for [exact product line]” page, matching product code or a manufacturer compatibility chart.
Retailer photos can help identify obviously different shapes, but a visual similarity is weaker than an official fit statement. A millimeter difference or locking-tab change can prevent installation even when two cartridges look alike.
Shade compatibility is a second check
A refill can physically fit and still not reproduce the shade system you expect. Brands sometimes revise shade names, add shades to a newer compact, or sell regional shade ranges. Confirm the exact refill shade rather than assuming a #21 from a different line uses the same undertone or depth.
If your compact line was reformulated or relaunched, check whether the brand describes the new refill as backward-compatible. Do not infer compatibility from the old and new products sharing a shade number.
Compact + refill sets are easier to verify
A listing such as “15 g + 15 g refill” sold as one set gives strong evidence that the included refill fits the included compact. That evidence applies to the set. It does not prove that an unrelated 15 g refill from another brand or line will fit.
Keep quantity separate from hardware. A set can include one compact plus one refill; a refill-only listing may include no outer case; a two-pack can contain two complete compacts. Read the configuration before comparing prices.
Before buying a refill
- Read the brand name on the compact.
- Identify the exact cushion line, not just the shade.
- Find a refill page that names that exact line.
- Check compact/cartridge code or dimensions when available.
- Confirm the refill shade and regional shade naming.
- Use gram weight only for quantity/value comparison.
- If fit is still ambiguous, buy the full compact or obtain manufacturer confirmation rather than forcing the cartridge.
FAQ
Are all 15 g Korean cushion refills the same size?
No. Weight is not a physical standard for the cartridge. Case dimensions and locking systems can differ.
Can I use a refill from another line by the same brand?
Only when the brand explicitly states cross-compatibility or the refill is sold for both lines. Same brand alone is not enough.
If the shade number matches, will the refill fit?
No. Shade numbering and cartridge fit are separate systems.
What if the brand does not publish dimensions?
Use exact line/refill naming or manufacturer confirmation. Do not invent dimensions or assume fit from product weight.
Current verification sources
- JAVIN DE SEOUL: Wink Cushion Glow Pocket Refill 8 g.
- JAVIN DE SEOUL: Wink Cushion Glow Refill 16 g.
- Connected ProtoClinical Shopify catalog, checked September 15, 2026, for current cushion/refill titles and configurations.
Verification boundary: no manufacturer dimension chart or statement proving cross-fit between the 8 g Pocket and 16 g standard JAVIN cartridges was found in the sources checked. They are therefore treated as separate compatibility families.
