This is a large size, handle, cool rainbow metallic color, great lid thats a screw top with a flip top and air hole making it easier to sip. Keeps my tea hot for hours. Very nicely packaged and I even got a coupon to use on a future purchase. I will be buying more. The Beast is a great purchase! Review: Beast vs. Stanley - I can’t say enough about this cup. I bought it January 2023 and it’s January 2026 now. I got a Stanley for my birthday as a gift so I compared the two. My $30 dollar rainbow beast to the $50 Stanley glitter bomb. The quality is absolutely amazing on both cups my drink is cold and still has ice after 14 hours I haven’t tested for hot in my 40oz but I have the 20 and it keeps my coffee hot through lunch. I love the design and colors offered on beast the rainbow is my favorite. The beast tumbler is lighter than the Stanley and I prefer the removable cuff handle that I have for the beast tumbler. Car cup holder though the Stanley was a better fit but it’s really tall. My beast fits in the cupholder if I had the coaster in the bottom of the cup holder so eh not a big deal. The one thing I like the Stanley over the beast is the lid. The beast has an opening so that you can use it with or without a straw so bugs can get in hair/dust while the Stanley is closed top 100%. I love both cups but for quality and bang for your buck beast is the winner. ## Features - EXCLUSIVE BONUS BUNDLE - Offering unrivaled value for money: 2 unbreakable straws: 1 curved; great for water + 1 wider & straight; ideal for shakes & smoothies + a straw brush & our upgraded pop up lid for super easy cleaning!

My milky tea gets inside and is starting to get crusty/flaky...** A: I have the older version of the lid too. It usually comes out clean if you put it through the dishwasher but needs a good shake afterwards. You can also try holding it sideways under warm running water for a min and then vigorously shake it over the sink. Try the other side and repeat. Do this with the lid closed and opened. **Q: Is there a way to keep the straw from rattling around? I use it in a quiet office and it so noisy.** A: You can get silicone bumpers that slide onto the straw on either side of the lid, to hold the straw in place and keep it quiet. Some products even come with tips as well as bumpers, in case you don’t care for the metal straw hitting your teeth. Amazon sells them. I have had zero rattling since I started using them, and I enjoy the tips, no burning your lips on a hot straw. **Q: Just got mine in and I love it. I can tell I’ll need more straws so what size should I get? I like the wide straight one. What size is it?** A: I have a 40oz Beast which I love. I use the metal extra long straws, however, the regular size metal straws can work. **Q: Can u use this cup without the straw** A: Mine has no vent which makes it difficult to get much liquid out. I’m considering returning it as I don’t like drinking out of a straw. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Everything I was looking for! *by K***Y on February 4, 2026* I was impressed at the quality for such a cheap price.

With that said and the shipping issue aside, I am very pleased with this purchase. The tumbler is of very good quality and retains hot and cold drinks as expected. The lid is very secure and the inclusion of two stainless steel straws and a pipe cleaner is much appreciated. Fits well in my vehicles cup holders. Very pleased with this quality product. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.vn/products/185939965-beast-30-oz-tumbler-stainless-steel-vacuum-insulated-coffee-ice](https://www.desertcart.vn/products/185939965-beast-30-oz-tumbler-stainless-steel-vacuum-insulated-coffee-ice) --- *Product available on Desertcart Vietnam* *Store origin: VN* *Last updated: 2026-05-21*
