Wallet-Sized Stain-Treatment Card Development
Budget: $30 – $250 USD
Product overview
Wallet-sized fabric stain-treatment card called Ready. — fits in a standard card slot, not a bag or pocket
Pop-off cap reveals a wide felt applicator tip for controlled application on fabric stains
A flat internal reservoir holds the treatment liquid; a capillary wick feeds it consistently to the felt tip without leaking or oversaturating
Multi-use: designed to deliver roughly 15-25 individual stain treatments before the reservoir runs dry, then the whole card is discarded
Target specifications
Dimensions: 86mm x 54mm x 3.0mm (standard card footprint)
Format: slim, rigid, wallet-sized card
Closure: leak-resistant pop-off cap with a silicone gasket seal
Finish: premium matte, fingerprint resistant
Materials (concept, open to designer's recommendation)
Outer shell + cap: PP (polypropylene), injection molded
Felt applicator tip: polyester/viscose blend, high absorbency, low lint
Cap seal/gasket: silicone
Internal reservoir: PP or PE, low-profile, chemical resistant
Wick: non-woven, optimized for consistent flow and saturation
What I need from you
Manufacturable CAD model (STEP/SolidWorks files) built from this concept
A first 3D-printed or resin prototype to check size, fit, and cap action
Design-for-manufacturing (DFM) review so the design is ready to quote with an injection molder
Recommendations on tooling, materials, and mechanism reliability (cap seal, wick flow) at this scale
