Meet your new everyday go-to: Fun Cases' Doechii tumblers are big, bold and built for non-stop sipping. These 40oz insulated cups come with a comfy handle and a sturdy straw, giving you that Stanley-style feel but with Fun Cases flair. They’re perfect for iced coffees that last through back-to-back lectures, smoothies between shifts, or bottomless hydration at festivals.
Made from tough stainless steel with double-wall insulation, these tumblers keep drinks cold for hours and stop condensation dead in its tracks — no more soaking your desk or bag. The lid fits snugly, the straw is BPA-free, and the base sits steady on uneven surfaces. Drop it, tote it, or lean it against a lecture theatre seat; Doechii tumblers are built to handle real life.
If you’re after something to take everywhere, our Doechii travel cups are lightweight enough for day-long carry and roomy enough for all the extras — ice cubes, protein shakes, or a giant iced latte. They’re designed for people who move fast: students, athletes, commuters and anyone who refuses to let a single sip go to waste.
Style matters. These cups come in vibrant colours and matte finishes so you can match your vibe, your locker, or your aesthetic Instagram flatlay. They make great gifts for friends who love practical-yet-pretty gear, and they’re easy to personalise with stickers, charms, or your own doodles.
We care about the planet as much as we care about your caffeine. For every order, Fun Cases plants a tree, helping offset our footprint and making each cup a little greener. Plus, we offer free worldwide shipping (minimum spend applies), so your Doechii cup can travel as far as you do.
Cleaning’s a breeze: pop the straw and lid parts for a quick rinse, and the main body wipes or washes without fuss. That means more time out and about and less time scrubbing. Whether you’re prepping for a study sesh, heading to a training session, or chilling with mates, these tumblers keep up.
Picking a new water bottle should feel fun, not frustrating. Our Doechii tumblers blend durability, style and practicality into one reliable companion for daily life. If you want a cup that looks ace, lasts ages and doesn’t let you down, you’ve found it.
