Wholesale Custom Bottle Koozies | Standard & Magnetic Series Factory Supply

• No. This specific model is precision-engineered for 16oz to 25oz (500ml-750ml) standard sport bottles. Our 15.0cm height is the industrial standard for these capacities, providing optimal stability and balance. For oversized 32oz flasks, the weight often exceeds the safety threshold for standard carry—our focus is on delivering a secure, perfect fit for the most common 16oz-25oz fitness bottles.

• Our premium 15.0cm bottle koozies are engineered for a universal, high-performance fit. They are specifically designed to accommodate most 16oz to 32oz sport water bottles and stainless steel flasks. The 15.0cm height ensures maximum surface coverage for insulation and protection, while the flexible 3mm neoprene core adapts perfectly to both narrow and wide-mouth bottle shapes.

• Yes. As a 24-year source factory, we take compliance seriously. Our neoprene SBR core and polyester linings are fully REACH, RoHS, and California Proposition 65 compliant. We provide material safety data sheets (MSDS) upon request to ensure your bulk orders pass any local import audit or corporate sustainability requirements.

• Logo clarity is a synergy of the material base and the printing process. While we provide a specialized 200g+ double-white polyester base to prevent rubber-core bleed-through, a perfect result also depends on professional execution.
• Our Factory Standard: We use 300+ DPI high-definition transfer paper and calibrated industrial heat presses to ensure the exact balance of temperature, pressure, and time.
• Troubleshooting: If you are sourcing material for your own printing, please ensure your transfer paper resolution is sufficient and your machine parameters are audited to prevent “ghosting” or fading.
• The “Pro” Solution: For logos requiring extreme detail or placement over complex patterns, we recommend Offset Heat Transfer (DTF) on top of the sublimated base. This provides a crisp, raised-texture logo that “pops” against any background.
• Contact our engineers for a free printing audit of your artwork.

• We support business growth at all scales. Our MOQ starts at just 12 units (1 dozen) for stock patterns. For bulk custom orders, our standard production lead time is 7-15 business days after digital proof approval. We typically provide your digital layout for audit within 48-72 hours of receiving your vector files.

• We highly recommend it. We provide one free stock sample (you only cover the shipping fee) so you can personally audit the material texture, magnet strength, and stitch quality. If you require a custom-printed sample with your logo, we offer a rapid prototyping service for a nominal fee, which is often refundable upon your first bulk order.

• To maintain the structural integrity of the neoprene and the high-strength magnets, we recommend hand washing with mild detergent and air drying. While the materials are durable, avoiding high-heat commercial dryers prevents pattern distortion and ensures the embedded magnets remain perfectly positioned for years of service.

• A 15.0cm height provides the optimal center of gravity for standard 16oz to 25oz bottles. Unlike retail 10cm sleeves that allow bottles to tilt or slip, our industrial high-coverage design locks the bottle in place during high-intensity movement, ensuring a 100% secure fit for fitness and outdoor use.

We exclusively use industrial-grade N52 Rare-Earth Magnets. These are secured within a Shielded Embedding Layer inside the 3.0mm SBR core. This construction ensures the magnetic field is directed outward for maximum grip without compressing or interfering with the neoprene’s thermal insulation properties.

Yes. Our N52-embedded protocol is tested to support a fully loaded 16oz (500ml) to 25oz (750ml) stainless steel bottle on vertical industrial metal surfaces. The 15cm SBR grip surface creates the necessary friction to prevent sliding, even under full weight. (Note: Not recommended for oversized 32oz flasks due to weight-to-magnet ratio safety standards.)

For professional sports gear, 4-Needle 6-Thread Flatlock Stitching is the industry standard. It provides a flat, high-tensile seam that resists bursting under the repeated tension of gripping and pulling, unlike the standard zigzag stitches found in promotional-grade sleeves.

We support growing brands with a 12-unit MOQ for professional sampling. This allows you to test custom textures, such as our #11 Shark Skin or minimalist matte finishes, before scaling to bulk factory-direct production.
