Description
This 1 oz amber cosmo round PET plastic bottle has a 20-410 neck finish. Its slender, tall body and rounded shoulders give a sleek, retail-ready look that stands apart from standard cylinders. The amber tint is a traditional choice for oils, tinctures, and light-sensitive products.
It is made from PET, a rigid plastic known for clarity and good impact resistance, so it holds its shape and stands up to handling and shipping.

- Neck Finish: 20-410

Ideal For
Essential oils, tinctures, serums, beard oils, fragrance oils, and other small-batch liquids. A good fit for skincare, aromatherapy, wellness, and cannabis brands.
