Smooth 33-400 Straight Sided Flat Threaded Closure

What this packaging is

A flat-top, straight-sided profile and glossy white finish give this 33-400 PP closure a clean, polished look that works across a wide range of container styles. The Smooth 33-400 Straight Sided Flat Threaded Closure pairs with any standard 33-400 neck finish, making it a practical, reliable cap for lip care, eye treatments, face moisturizers, body scrubs, hair treatments, and body lotions. Made in Europe with consistent quality standards, it ships fast from US warehouse stock in California and New Jersey. Accessible minimums make it a smart option for emerging brands or limited-edition runs testing new SKUs.

Why brands choose this

• US warehouse stock cuts wait times dramatically: With inventory held in both California and New Jersey, brands can receive product quickly without the lead times that come with overseas ordering — a real advantage when launching a new SKU or managing tight timelines.
• 33-400 neck compatibility opens up a wide container range: This closure threads onto any standard 33-400 neck finish, giving brand teams flexibility to pair it across multiple container formats — bottles, jars, and tubes alike — without committing to a proprietary system.
• Accessible minimums built for test launches and indie brands: Starting at just 50 units, this closure removes the order-size barrier that often stops smaller brands or limited-edition projects from sourcing quality closures — letting teams move from concept to shelf without overcommitting inventory.
