Shineful

I have to admit it was well worth the wait. I love it. I have ice almost 24 hrs after I fill up my tumbler. It keeps my drink cold all day and over night too.

The quality of the leather is exceptional and the intricate details inspired by classic literature make them unique. Highly recommend.

I'm not usually one to leave reviews, but I had to share how impressed I am with Shineful. The attention to detail is remarkable.

I love this insulated cup. It is large. I hesitated because of the size but am I ever glad I went for it. It keeps my drink cold or hot for the entire day. Best ever for busy people who don’t have time to keep refilling their drinks includes moms who are asked to share. you will love it.

I bought this because it was nice looking, and I fully expected there to be a tradeoff between style and performance. But this thing is really well made, keeps my ice water cold for longer than I need it to, and is more than just nice looking. My only quibble is that after having it for a few months the draw on the straw can be a little blocked, it doesn't flow easily, and I can't figure out why. But most of the time it works great, and if anything, it's the best insulated tumbler I've used yet. The included plastic straw is okay, but I prefer the metal straws I bought.

This cup is not a Stanlet. In my opinion it is better. I performed a leak test with this cup and 2 other popular brands and this cup was the winner. Not sure how it is compared to keeping things cool but it does a great job for me.

I love the sleek design of these tumblers, and how they fit nicely in the car! They keep my water nice and cold daily, and the 40 oz makes it easy to sip on water throughout the day. The mint color is so cute, and I love how easy it is to clean - no nooks and crannies for mold to grow!
