These are various quantities of 8oz Cobalt Blue PET (Polyethylene Terephthalate) oval shaped bottles, also known as Cosmo Ovals or Cosmovals.
They are transparent blue in color, 120ml or 4 oz capacity, and each one comes with either a screw-on cap, a disc top dispensing lid (metallized gold, white, or black), or fine mist pump sprayer / atomizer attachment (black or white).  The neck size of the bottles is 20-410.
These are great to hold hand sanitizer, cosmetic products, and many other liquids..  Their small size makes them particularly convenient for travel. Orders will be shipped in a padded bubble mailer through USPS First Class and USPS First Class International.  Please let us know if you have any questions.
