Wallet-Sized Stain-Treatment Card Development/Prototype

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
