This Review Title is Useful but not made well. and the content is: I was happy to find these so we could attach to the outside of my kid’s backpacks and sports bags since with covid, they need easy access to hand sanitizer. Unfortunately, after about 2 weeks one of the caps would no longer snap shut. Also, one of the carabiners arrived broken and would clip shut. Its a month later and more of the flip caps have broken. Wish these were made better..There are other information for this review, one is This reviewer did purchase it and the other is 4 people think this review is helpful.
