The Tumbler Was a Coffee Gadget Before It Was a Gundam
The hardware under the paint job is not Bandai's. BEAN is an existing product from thermo mug, a Japanese drinkware brand founded in 2000 that builds double-wall insulated bottles and tumblers. The BEAN body is a tall 350ml cylinder sized so a pour-over dripper sits directly on the rim, which means you brew into the tumbler, screw the lid on and leave with it. The brand sells the standard version in three coffee-named colors, ESPRESSO, CAPPUCCINO and LATTE, for ¥3,850 on its own store.
The STRICT-G collaboration keeps that body and changes the finish. One tumbler is built around the Gundam, the other around Char's Zaku II, both rendered in a chibi style Bandai calls otona kawaii, or adult-cute. Bandai is pitching these as everyday drinkware rather than shelf pieces, in line with the rest of STRICT-G's September output: the label also put out a reversible Unicorn Gundam souvenir jacket and a set of shirts with embroidered Zeon and Mafty emblems this month.
What ¥5,500 Buys
Both tumblers hold 350ml, roughly a coffee-shop medium. The screw-on lid seals fully, so Bandai is comfortable telling buyers to drop one in a bag. The opening measures about 85mm across, wide enough to fit a hand inside for washing, and the lid breaks down further into its inner cap and gasket for cleaning. The body has a scratch-resistant powder-coat finish that Bandai describes as pleasant to the touch. Underneath it, vacuum double-wall construction keeps hot drinks hot and iced drinks cold. Bandai's press materials list the build as stainless steel, silicone rubber and polypropylene.
That works out to a ¥1,650 premium over the plain BEAN for the licensed artwork.
How to Get One
Pre-orders run through the STRICT-G Online Store inside Premium Bandai, opening at 1:00 p.m. JST on September 29, 2026 and closing at 11:00 p.m. on October 12. Shipping is scheduled for October. Bandai notes that sales can end early if the prepared stock runs out, which is standard language for Premium Bandai runs and worth taking seriously on collaboration items.
In-store sales start October 10 at four STRICT-G locations, according to Anime Anime: Tokyo Odaiba, Tokyo Solamachi in the Tokyo Skytree complex, NEOPASA Shizuoka (outbound) and Taga SA (outbound). The last two are shops inside expressway service areas, so half the physical points of sale are effectively car-only.
Looking Ahead
No international release has been announced. Premium Bandai runs an English-language storefront with its own STRICT-G section, but the tumblers are currently listed only on the Japanese side, so overseas buyers are looking at a proxy service or a friend in Japan for now.
As for the source material, Mobile Suit Gundam first aired in 1979 and is credited with opening up the real-robot genre: the branch of science-fiction anime that treats giant machines as military hardware rather than superheroes. The original 43-episode series streams on Crunchyroll with English subtitles, which covers the full run of the Zeon mass-production Zaku II and the red commander unit Char Aznable made famous.
