These Tovla plastic squeeze bottles are the ONLY brand i was able to find on Amazon that met all my requirements.
Pros: 1) They are HDPE unlike almost all the others and thus the safest and most nonreactive of all the plastics currently out there and definitly safer than PET
2) they have a cap that screws on an off not like those little red caps that don't screw. The cap will never fall off and get lost, and contents wont spill if tipped over or upside down.
3) the screw cap covers the nozzle completely thus ensuring it stays SANITARY. Fingers never need touch the nozzle.
4) the company is responsive and approachable making it a pleasure to do bussiness with them.
5) and it just so happens that the 8ounce bottle is the perfect size to nestle perfectly within my fancyfeast alcohol stove to store fuel (photo included) . And the bigger 16ounce bottles work great for oil in the kitchen,
6) the measurments on the bottle are bold and crisp and look like they will last a long time.

Cons: 1) i cant find the letters HDPE anywhere on the bottle, nor is there a recycling symbol. I can only take the manufactures word for it that this plastic is indeed HDPE. As a rule i dont like to blindly takes someones word for something, especialy a manufacturer and this is why i gave these bottles a 4 instead of a 5. There is a 1 on the bottom of the bottle and that gave me doubts but then i discovered that HDPE comes in a version called 1 or 2. But still....

Very convenient, take up minimal space, and find I use more than expected. Good price and would buy again.

I use these bottles for dispensing polyurethane resin, and they're honestly great for that purpose. Generally, I have difficulty finding lids that do not leak, even though most bottles like these are marketed as leak-proof. I was surprised to find that in the lids of these bottles, there is a small pad that creates a seal when you screw it on. So far I haven't had any leaks or spills out of the bottles, and the caps on top are really convenient for keeping unwanted air out of the bottles.

These bottles are also clearly marked with OZ and ML, so it's easy to measure if you need to do so.

I think that these would also make great condiment bottles, or for holding fluids in the garage that you need to use regularly. Overall, I'm very pleased. I'll be ordering more of these soon.

These are great for my needs. The quality is great and so far no leaks. I just purchased more.
UPDATE: I ordered these a 2nd time and they were not the same, I spoke with someone from Amazon and they assured me I would get the correct ones. Well the 3rd order came today and they were just like my 2nd order WRONG. I'm so disappointed. I really like my 1st order/batch of bottles because they are the ones advertised, and have the white screw on lids that work great but I received the little red lids AGAIN that do not work well !! :( :(

Ounce and half ounce markings, reliable soft washer in top, vinegar and oil mix shaken vigorously - NO LEAKAGE at all. None. Not even a film of tiny leakage around the top after shaking the crap outa it. Love a well made product that does exactly as claimed.
PS ... The wonderful little collapsible funnel with small indents on the sides of the spout to allow air passage when filling a bottle ... fits opened top of the bottle perfectly. Very useful. Easy to clean. Love it so much that if I ever lose the funnel, I would order a whole new complete package to get one.
Love products that do exactly as claimed in ways I hadn't even thought of.
