Plastic Mason Jars with Handles and Straws - 20 oz Insulated 4-Pack

Our review of these Plastic Mason Jars with Handles and Straws finds them best suited to families and casual entertainers who want a sturdy, attractive drinking option that keeps cold drinks chilled. The single biggest reason to consider this 4-pack is the double-insulated design that helps drinks stay cold longer while the wide mouth and handle make them easy to fill and carry. They are a practical, BPA-free acrylic option for everyday use where break-resistant drinkware and a familiar mason jar look are desired.

Key Features

• Classic mason jar design: The wide-mouth jar and comfortable handle give a homey look and make pouring, stirring and drinking simple for adults and kids.
• Double-insulated construction: The insulated walls slow temperature transfer so cold drinks stay chilled and condensation is reduced on the outside of the cup.
• Includes lids and straws: Each jar comes with a colored lid and matching straw which reduce spills and make the set convenient for on-the-go use.
• BPA-free material: Made from BPA-free acrylic for safer food contact and a lighter-weight alternative to glass that resists shattering.
• Versatile use: These tumblers work at home, the office, poolside or camping thanks to the spill-reducing lid and durable construction.

Who It's For

This set is ideal for households with kids, casual gatherings, or anyone who wants the mason jar aesthetic without the fragility of glass. The 20 oz size and included straws suit iced beverages, smoothies and water, and the handle makes them comfortable for carrying around the house or yard.

Those who need exact volumetric accuracy, a true glass feel, or fully dishwasher-safe tumblers may prefer to look elsewhere; handwashing is recommended and a few users noted variation in perceived capacity and occasional seal issues under heavy use.
