Mr. Pen- Shaker Bottles for Protein Mixes, 28 oz, Leak Proof | Shaker Cups with Stainless Steel Wire Whisk Ball for Protein Shakes and Pre Workout

After having it for two months is was really cheap no leaks or anything. It works really good. I use it for the gym three times a day for different liquids. Just what I wanted for the price. 8/5/26.

I don't normally write reviews, but they sent a mustache sticker and a really nice thank you note. I will say, anyone who says it leaks, must not have closed it tight enough. I had the same issue and thought I wasn't going to be able to shake it. Turns out, it just wasn't closed all the way. Great product. Simple and gets the job done. I used whey protein powder and milk and it was very smooth. I'd definitely recommend.

After doing a bit of product comparisons and reading reviews, I recently ordered the 28 oz Mr. Pen shaker bottle and a 25 oz BlenderBottle Sport Sleek insulated stainless steel shaker bottle (which was about 3 times the price at the time). I have used both several times now, making the exact same shake each time. My initial concerns for the Mr. Pen shaker were 1) that it might not mix as well since it didn't have a rounded bottom like the BlenderBottle had. This proved absolutely not to be the case. The Mr. Pen mixes significantly better, maybe it's the different shape of the shaker ball or maybe just the extra 3 oz of space in the bottle, but hands down Mr. Pen wins. 2) The lack of the locking lid like the BlenderBottle. This proved to be not an issue. It snaps closed solidly and easily. 3) Not being insulated. Also ended up not being an issue for me really. My advise, at a third of the price, go with the Mr. Pen version for sure.

I love it so much! Its really good considering the price, i was prepared for leaking or maybe a small sized bottle but its really good! It doesn’t leak, has no weird taste, easy to clean and the size is great!! It also has measurements which is really helpful since i mostly eyeball every drink :)

★★★★☆ Great shaker bottle, but cap could be improved This shaker bottle works well for mixing protein shakes and pre-workout. The stainless steel whisk ball does a good job breaking up clumps, and the 28 oz size is convenient for workouts and everyday use. My only issue is that it does occasionally leak. The lid closure is not as secure, and you have to hold it closed when shaking. I have to make sure I am holding the cap closed securely when shaking it, which can be a little inconvenient. Other than that, it is a durable and useful shaker bottle that gets the job done. The cup does come in a variety of colors, it is a cute quality!

Good quality bottle. Exactly what i needed. I like the mustache. Thank you for the extra note left. Means a lot to receive a short message of appreciation for purchase. Thank you!!!

There was a handwritten note in it so sweet! And some cute stickers so thoughtful and exactly what I was wanting. Thank you so much!

This thing leaked from day one and never got better. I was bummed, because I really wanted to carry this around in the gym with me to every workout station. Oh well, I guess I'll stick with a cheap bottle of water for the time being and look like a loser.

Exactly what I was looking for

Lovely! Love the color and price! Very pleased! Thank you.

This cup works great! The shaker ball is amazing mixed up my powder super fast and no leaks! I love the mustache sticker and the note that comes with it!!
