7 Pack pH Test Strips, 560 Strips pH 1-14 Universal Litmus Test Paper for Soap Making Water Wine Saliva Urine Soil Pet Food Testing (Storage Case)

I bought these to test the Ph of skincare products, because my skin can get alllll angry if I'm not careful. These work almost instantly, it's a nice big test strip so easy to read, soyou're not squinting at the color chart, and they're a really good deal. I will probably not use even half of these before they expire, but I will buy them again when that happens.

The package arrived on time. They are easy to use, and the pH values are accurate based on the colors on the table after testing. Very easy to read, the size is small, but it is perfect for its purpose. Good quality. I used them to check my homemade skin care cream and the acidity of my homemade apple vinegar; the accuracy was perfect. I will purchase again.

Bought these to test the ph of my fish tanks before adding triop eggs and they worked perfectly and were very easy to read! Triops are extremely sensitive to ph and they hatched within 24 hours so id say these are very accurate strips.

Seems to work okay I don't another tester so can't compare, but I did my apple cider vinegar and it read were it was supposed to be They are easy to use Inexpensive. Paper is thick enough not to fall apart easily when wet Seems to be accurate

These strips are very straightforward. I love that they come in two separate packs so I can keep one in the kitchen and one in the garage. The paper is sturdy enough that it doesn't fall apart when wet, and the 1–14 range covers everything I need. Great for quick checks without needing a digital meter.

I love this stuff!! I use it to check the pH of my syndet bars. It works amazing! I constantly check it with other products but is always spot on on its accuracy. The colors are easy to read and know what the actual pH value is. I will continue to purchase this product.

Poor quality reading. If you put more than one drop on the paper, it is unreadable. Even with one drop, it only changes color for a short amount

These universal pH indicator papers are easy to use and come in a handy matchbook-style pack, which makes them super convenient for quick testing while I’m making soap. The color chart is clear, and the strips seem accurate — I’ve gotten the right color range every time so far, and it matched the pH I needed perfectly. The reason for three stars is that the paper itself is very thin and could definitely be made thicker for easier handling. It tends to feel a bit flimsy when dipping into liquids. However, for the price, they do exactly what they’re supposed to and get the job done without any major issues.

A described. Good value.

bought for my boy, he likes testing everything with it

they work! however if you're after any kind of accuracy do yourself a favor and get a digital PH meter. don't learn the hard way like I did.

I bought the wrong strips. That work for sure. But there not accurate enough for me

Bon prix.
