Product Description

Tiny jars deserve a little color, too! Give your 4oz regular mouth jar a softer grip, or use the closed-bottom sleeve on its own as a tiny cup.

  • Jar fit: Sized for tiny 4oz (½ cup) regular mouth Mason jars.
  • Grip and cushioning: Flexible silicone adds grip, cushioning against bumps, and light insulation.
  • Everyday uses: A handy size for baby food, espresso, condiments, and snacks. The closed bottom also lets the sleeve serve as a tiny cup for dips, snacks, or a pup-cup.
  • Design details: The bottom has no hole, so the sleeve can also be used on its own as a tiny cup.
  • Material: FDA-grade silicone rubber; BPA-free.
  • Sleeve care: The sleeve is dishwasher, microwave, and freezer safe. Wash it separately from the jar to avoid trapped water.
  • What is included: Single-color options include one sleeve; multipack options contain the quantity and colors listed below. Jars, lids, and straws are sold separately.
  • Americana 4pk: One sleeve each in Deep Blue, Frost, Leaf Green, Cherry Red.
  • Enchanted 4pk: One sleeve each in Aquamarine, Berry Pink, Charcoal Gray, Ultra Violet.
  • Core Colors 6pk: One sleeve each in Deep Blue, Frost, Charcoal Gray, Leaf Green, Cherry Red, Ultra Violet.

I purchased the silicone sleeve for myhand soap jars

I purchased the silicone sleeve for myhand soap jars. I found that when I pushed down to dispense soap the jar would slip and fall on its side and leak. Not good so I wanted to try the silicone sleeve for a low support and it’s perfect. I’m so happy with this and will only use the jars with the sleeve from now on.

Love the sleeves!

I think these are such a good idea! I have already put the ones I have to good use on my kitchen counter, and they are looking good! Not to mention the fact that they make it much easier to pick up the jar it is on! Thanks so much for a great item!

Love my new spice jars!

I bought the sleeves & spice jar lids. They are great for camping. The 4 oz jars hold lots of salt & pepper. The lids are good for measuring or pouring or sprinkling. The sleeves make them easy to hold & safe if they drop.

Love these, they fit snugly but are easy to remove to clean. Very sturdy, quality product.

I didnt understand that the jars were separate. Do you have the short jars to fit?

Simple & Great

My wife and I are using these sleeves for baby bottles and toddler sippy cups. My main concern was how effectively they would hold up to our toddler’s testing gravity with a mason jar cup. It didn’t take long for the kiddos to try it out, and the mason jars are just fine! These sleeves protect the glass from shattering all over the floor, and are easy to clean.

Just what I wanted.

I was looking for a protective cover for my mason jar that would block light (to preserve the contents better). This sleeve fit perfectly, doesn't fall off but is easy to put on. It is a nice thickness with a cute design and does all I had hoped. So, I bought more. :)

Great addition to the mason jar that can be protected.

Nice quality

I got these for baby bottle covers and baby food jars. They’re thick and good quality. Easy to put on, but they don’t easily fall off. Nice selection of colors too.

Adorable, perfect fit

These were the perfect fit, not too snug that you couldn't remove them, but not to loose that they fall off. They protect the jars, which is perfect because I'm using them for home made mason jar bottles

Slippery when wet

These sleeves (8oz and 4oz) do not fit snuggly enough in my opinion. They have decent grip when dry, but if they get the slightest amount of moisture ie. a dribbly toddler using a straw top on an 8oz jar, the sleeves slip right off. Fortunately the 8oz did not break, but we did lose a 4oz jar of baby food, again the jar sliding out of the sleeve when it encountered moisture from the food.
From prior experience with other-brand glass water bottles and fitted silicone sleeves, the sleeves should be a real struggle to don/doff.

I use 4 oz. jelly jars to hold my essential oil personal care products that I make for myself and my family. However, I was concerned about having glass in the bathrooms and showers. These silicone sleeves fit on the jelly jars perfectly, and everyone can have their own colors. I like using glass to hold my oils and lotions, and now I can feel secure knowing they are safe and protected.

Perfect for my glass Mason jar baby bottles, and my 4 year old seems to think the little "cups" are the perfect size for her too!
