SLifeJars 4oz Plastic Jars 48‑Pack Clear Wide‑Mouth with Black Lids — Airtight, Stackable Storage

These are SLifeJars 4 oz clear, wide‑mouth PET plastic jars — a 48‑piece set with black screw lids, labels, and a marker designed for airtight, stackable storage of cosmetics, food samples, slime, and small items.

SLifeJars 4oz plastic jars combine a transparent body with a wide mouth and screw‑on black lid to make filling, cleaning, and identifying contents fast and convenient. Made from lightweight, durable PET plastic, the containers are reusable and stackable for neat shelving or travel. This package arrives with 48 jars, 48 labels and one marker so you can organize sets for beauty products, kitchen condiments, craft supplies, or DIY slime projects without searching for extra accessories.

How do these jars keep contents fresh and secure?

The jars use screw‑top black lids that create a dust‑resistant closure and reduce air exposure, helping to preserve texture and fragrance longer than an open container. The clear walls let you check levels at a glance so you know when to refill.

• Threaded screw lids for a tight mechanical seal
• Clear PET construction for visible contents and portion control
• Dust‑resistant design suitable for cosmetics and crafts
• Included labels to track dates or product names

What practical uses do these 4 oz jars have at home or for small businesses?

At 4 ounces, these jars are sized for single‑serve condiments, sample cosmetics, travel toiletries, and small craft projects like slime or beads. Entrepreneurs selling samples, subscription boxes, or handmade balms will find the set useful for packaging and presentation.

• Meal prep: sauces, spice blends, and dressings
• Beauty: creams, scrubs, lip balms, and travel samples
• Crafts: slime, glitters, beads, and paint mixes
• Retail/sample use: compact, uniform packaging for product demos

Are these jars easy to clean, travel with, and reuse?

The wide‑mouth design makes hand‑washing and product removal straightforward, and the lightweight PET material keeps baggage weight low. The manufacturer recommends hand washing only and avoiding hot items to preserve shape and closure integrity.

• Wide opening for easy scooping and cleaning
• Lightweight, durable PET for repeated reuse
• Portable size fits in purses, toiletry bags, and craft kits
• Not dishwasher or microwave safe — avoid hot contents
