DO NOT, whatever you do, fill these bottles with sanitizer. I got too caught up in the stars and the words, “sturdy,” “strong,” and “resistant to breakage,” that I neglected to read the actual reviews. Don’t get me wrong, these bottles looked great. They would have worked for our needs. However, 7-10 minutes into pouring sanitizer into these, the bottles (yes plural) began to crack. I picked one up and the bottom came crashing down on to my kitchen counter. Lesson learned. Read reviews before purchasing.
