Lifefactory Flat Caps for 4-Ounce and 9-Ounce BPA-Free Glass Baby Bottles, White (Pack of 2)

Has worked well without any issues

Fits perfect! No leaking, easy to wash and sterilize.

good quality. good price. fit perfectly . made it possible to reuse an old baby bottle.

Drink bottle caps can be an easily misplaced or abused item, given how many times they are washed and handled over their life cycle. A Lifefactory bottle can last for years, but the plastic caps take some abuse, so I am grateful the manufacturer sells extra caps separately. These fit my 9 ounce bottles as they should, no issues other than the fact that these caps in general are harder to get properly threaded and fully on as compared to the lids on my larger bottles.

These have worked out great for me. I put the bottles in my cooler to transport extra milk/juice so I dont have to carry around several bottles. They work well and I have had no issue with the caps leaking. They also make great water bottles! Happy I purchased

I love all life factory products. I've been using only life factory for my family for the past 3 years. The only thing about the baby bottles and any of their lid products is that when they're dropped from any distance off the floor they break. For the cost, I wish they were more durable.

Those bottles are so expensive that if you happen to loose cup it is a mini tragedy. So having an option to buy just a replacement tops is fantastic. It saves tons of money because the bottle without the top is otherwise useless. It is great that they come in such a small set of two making it affordable purchase. Mine came in perfect new condition and fit perfectly my old bottles. Very happy with the purchase.

Fit my Life Factory baby bottles perfectly and keeps the liquid secure without spills. I can throw bottles with these lids in a bag without worrying if they will spill even if they aren’t completely upright. Also easy to clean in the top rack of my dishwasher so they are sterile to use over and over again.
