Idealpak 3.4oz/100ml 20-410 PET Boston Round Cosmetic Bottle

What this packaging is

A classic boston round silhouette in a TSA-compliant 100ml size, the 3.4oz/100ml 20-410 PET Boston Round Cosmetic Bottle is built for brands that need range-ready packaging across multiple categories. The 20-410 neck finish opens up a wide world of closure compatibility — pumps, disc caps, flip-tops — making it easy to adapt one base bottle across SKUs. At 4.06" tall and 1.69" in diameter, it's compact enough for travel retail and shelf-efficient for retail sets. Silk screen, heat stamp, and label decoration options support strong brand expression. Ideal for face cleansers, toners, hair oils, and body oils.

Why brands choose this

• Multi-category versatility across five distinct end uses: From face toner and cleansers to hair oil and body oil, this bottle's neutral boston round profile and 20-410 neck finish work across a broad product range — giving brand teams the flexibility to develop and range multiple SKUs around a single packaging format.
• TSA-compliant 100ml size unlocks travel retail: At exactly 100ml, this bottle hits the sweet spot for travel retail, airline listings, and on-the-go product formats — a growing channel that many beauty brands are actively developing for incremental revenue.
• Closure flexibility supports diverse dispensing formats: The 20-410 neck finish is one of the most widely compatible standards in beauty packaging, fitting pumps, lotion caps, disc tops, and flip-top closures. That compatibility reduces sourcing complexity and makes it straightforward to test different dispensing experiences without switching bottles.
