0.3oz /7ml 33-400 Straight-Sided PS Jar

What this packaging is

Straight-sided geometry and a clean 33-400 neck finish give this compact PS jar a precise, professional look that holds up across labeling and offset printing alike. The 0.3oz / 7ml format is purpose-built for sample sizes, travel fills, and concentrated topicals where a small footprint matters. Made in the USA from white polystyrene, the consistent wall profile keeps decoration results predictable and branding sharp. The 33mm diameter with 400 threading locks closures securely, making it a reliable fit for loose powders, balms, and topical ointments. A domestically produced jar that keeps sourcing timelines tight for US-based brands.

Why brands choose this

• USA manufacturing keeps your supply chain simple: Produced and warehoused in Somerset, this jar cuts lead times and removes customs complexity for domestic brand teams sourcing at scale.
• Straight-sided geometry unlocks reliable decoration results: The uniform wall profile creates a consistent surface for offset printing, so branding lands cleanly without the distortion risk common on curved or tapered formats.
• Small-format versatility across high-demand categories: At 7ml, this jar hits the sweet spot for sampling programs, travel retail, and concentrated product fills across loose powders, balms, and topical ointments — giving brand teams one SKU that ranges across multiple launch contexts.
