Yes! We happily ship all over the world. Shipping costs will apply, and will be added at checkout.

We definitely understand that international shipping can be expensive, so we always offer 20% off on international orders to help offset the shipping cost. Simply email our team at care@masonbottle.com and they will provide you with the discount code! 

For overseas deliveries, we recommend allowing 3-4 weeks for your order to arrive. Delivery details will be provided in your confirmation email.

USPS is our primary shipping carrier; however some of the heavier orders (new jar sets, etc) may ship UPS. 

You can track your order by logging into your Mason Bottle account and viewing your recent order.

While the majority of our orders ship within 4-7 business days (excluding weekends and holidays); this does not encompass all orders. Our factory works diligently to get all orders out of the door as quickly as possible, however there are many factors (low stock, out of stock, restocks, and staffing shortages) which may push the shipping outside of this window.

If you need your order quickly, most of our products are available for 2 day shipping on Mason Bottle's Amazon store.

If your order is stating it is delivered but you didn't receive it, we recommend contacting your local post office and inquiring about the missing package.

Please send us an email at care@masonbottle.com within 24 hours of your package stating "delivered" so that we can work alongside you in getting your package to you. Thankfully, technology has advanced so USPS scanners will track GPS coordinates and they are able to usually retrieve mis-delivered packages or locate them otherwise.

At Mason Bottle, we believe healthy doesn't have to be high end. Since glass baby bottles can be expensive, we knew making a bottle compatible with mason jars would help families save money, especially if they already have jars at home. Mason jars are also a cleaner and more cost-effective alternative to breast milk storage bags. Simply store breast milk in a mason jar, then add the Mason Bottle nipple to turn it into a bottle.

The width of a mason jar lends itself perfectly to a breast-like nipple shape that is easier for babies to latch onto.

What is it about the wide nipple? We can't say exactly, but we can tell you that we have shipped 20,000+ orders, and have a 3% return rate. If your baby didn't take to our nipple, please reach out to us at care@masonbottle.com; we would love to see how we can help.

When you look at the top of the nipple, you can tell which size it is by the pattern of the holes: 

Slow Flow: 1 Hole

Medium Flow: 2 Holes in a Straight Line

Fast Flow: 3 Holes in a Triangle Shape

Flexible Flow: Y Shaped Cut

You can see a visual diagram on our product page

Our nipples, straws and sleeves are made from medical grade silicone. 

We make all of our silicone nipples, silicone straw tops, silicone sleeves, plastic rings and plastic caps in the USA and we make our glass jars, stainless steel jars, and single-piece storage lids in China

On our Where It's Made and Why page, you can see detailed origin information. 

Yes! All of our products are dishwasher safe, but if you are using the metal lid and band, we recommend rinsing and immediately and thoroughly drying these pieces to extend their life. 

We recommend cleaning the bottle before first use. To sterilize the nipples, simply boil them in water for 5 minutes. We have a super informative blog post about sterilizing and cleaning, as well. You can check that out here. 

Absolutely! We have compiled a list of 6 bottle warmers that fit Mason Bottle's.  Check it out here! 

We do recommend to remove the silicone sleeve from the jar prior to using a bottle warmer, simply because silicone is an insulator and it can take much longer for the bottle contents to get warm with it on. 

You absolutely can! There are 2 different adapters available that streamline pumping in to mason jars. You can read more about them (and find the links to purchase them) right here on our blog.

All of our nipples are designed with our FussFreeTM Ventilation System. This dual valve system allows air to be taken in and milk to flow smoothly out with no air bubbles to help prevent gas and colic.

Bonus: Our system is flawlessly built into the top of the nipples, so no special tubes, collars, bags or extra pieces needed!

Yes! All of our products have been extensively tested and are free of BPA, BPS, Phthalates and lead. 

Yes! The metal rings are compatible with every Mason Bottle with the exception of the Cap to Plastic rings. 

No. Due to security reasons, we cannot edit or change billing information. If for some reason, your order is declined due to a billing address issue, please just update your address and resubmit your order.
