ASEVAT 1000ml/33.8 oz Narrow Mouth Round Chemical Container, Plastic Leak Proof HDPE bottle, Lab Reagent Bottles, Water Sample Bottles (2 Pcs)

I use these to store soaps for washing boats and cars, they are awesome. They have not leaked a drop yet and the plastic is durable enough that in case they fall off a boat onto the concrete they wont burst open. The screw on lid seals very tight and feels like a good quality product, I will be buying more of these now since they are made surprisingly well.

Good for alcohol samples. Spill proof. A bit expensive.

I needed a heavy wall storage bottle to replace a leaking pesticide bottle which had started breaking down and cracking. These were the perfect size, and appear to be good quality.

Perfect for my fuel additive

I am a one bag traveler. I have always traveled with Nalgene travel bottles because they NEVER leak. But the Nalgene bottle's mouths are just too wide. I wanted something that would be just as leak proof, but that would be more forgiving when pouring out. I will carry things like Dr. Bronner's soap and mouthwash and I don't want to feel like I have to be careful not to spill all of the contents, but I also need the mouth to be big enough that thicker liquids like shampoo can still pour out. I will carry them in Osprey's Ultralight Liquids Pouch, and together they make the perfect system for your 3-1-1 liquids bag. I am obsessed with efficient traveling, and this is the best solution I have found for carrying liquids.

Use these to portion fuel additive for my motorcycle, and keep them in my tail bag.

These are just as advertised. Heavy duty and good seals. Used for chain oil in my camping gear. No more leaks!

If I could squeeze these bottles, I'd give them five stars. Unfortunately, they're made of a very hard, rigid plastic material, so they're really only useful for low-viscosity substances like shampoo, body wash, and hair gel with a thin consistency. I had to order squeezable tubes for my conditioner and curl cream. Their size is great, though. Nice and compact, and a stack of two of them still leaves plenty of room at the top of my toiletry case. Thus far, I haven't had any leakage issues, but I've only used them once. I will add that the labels that come with them are kinda useless because they're hard to write on. So they're just one more thing to add to the trash.
