0.18oz (5g) Clear Plastic Jars with Round Top Lids for Oil #PK930-030302

Engineered for Oils & Liquids

Unlike standard cosmetic jars, the #PK930 series features a precision-molded thread design that ensures a tight closure. This structural integrity prevents leakage of low-viscosity fluids such as essential oils, beard oils, and cuticle serums during transit.

Crystal Clear Clarity

Manufactured using high-grade polymer to achieve glass-like transparency. This allows for immediate visual identification of contents (color/texture) without opening the jar, enhancing the customer unboxing experience.

Durability vs. Glass

Lightweight and shatter-resistant. Eliminates the high breakage rates associated with glass sample containers, significantly reducing shipping weight and replacement costs for e-commerce businesses.

Perfect for my beard oil samples!

“I was honestly skeptical about the ‘no leaking’ claim since I use these for beard oils, and oil goes everywhere. But I tested a few in my pocket for a whole day and zero leaks. The threads on the cap screw down really tight. They are crystal clear too.”

— Mike T., Austin, TX

Great for my nail art glitters

“I’m a nail tech and I have a ton of custom glitter mixes. These 5g jars are the perfect size. I love that they are super clear (not cloudy like the cheap ones I got from Amazon before), so I can see exactly which color is inside without opening them.”

— Sarah Jenkins, FL

Logo looks amazing on the lid

“First time ordering custom prints from here. I needed 500 units for a trade show giveaway with my spa’s logo. The print on the round top is sharp and didn’t scratch off. The jars are small but perfect for a single-use face cream sample.”

— Jessica B., CA

Solid little jars for travel

“Bought these to decant my expensive moisturizers for a weekend trip. They hold just enough for maybe 3-4 days of use. I dropped one on the bathroom tile and it didn’t crack, so the plastic is pretty good quality. Fits perfectly in my TSA bag.”

— Dave R., NY

Arrived fast and intact

“I use these for lip balms. Usually, when I order plastic jars online, at least 10% arrive cracked. These were packaged really well, all arrived in perfect condition. The screw top is smooth, no weird plastic burrs or sharp edges.”

— Amanda L., OH

Cute and functional

“Using these for cuticle oil samples for my clients. I was worried the oil might eat away at the plastic over time, but so far so good after 2 weeks. They look like glass but are lightweight. Super cute little jars.”
