What is Green Cow Garden? Get to know Kohei Ogawa and BG Bear

Born in 1975, Kohei Ogawa graduated from Tokyo's Asagaya College of Art and Design in 1997. He then worked as a freelance illustrator, creating for advertisements, publications, and TV programs. In 2013, he created the "Green Cow Garden" series, primarily using needle felt as a medium – he chose this material because he wanted people to feel its warmth when holding it. This style, characterized by a warm touch and gentle, therapeutic animal characters, has become his signature.

The most famous character in the series is BG Bear. Since 2015, Kohei Ogawa has collaborated with HOW2WORK, successively launching the Naughty Boy, BG Bear, and Green Cow Garden blind box mini-figure series, which have garnered a solid fan base among Hong Kong and Japanese collectors. This is the first time this universe will appear in collectible card form.

What is HOW2WORK CTC? From Labubu to BG Bear

HOW2WORK CTC (Collectible Trading Cards) is HOW2WORK's artist collectible card brand. The previous three series were all from Kasing Lung's The Monsters universe, which are the familiar Labubu cards; the third series was globally distributed by SAKA SAKA (excluding mainland China). Green Cow Garden Series 1 is the first time CTC steps outside The Monsters to explore a second artist IP, also globally distributed by SAKA SAKA.

Series 1 Box Configuration: 42 Card Types, 137 Regular Card Variations – How to Interpret?

The officially announced core specifications are as follows:

• 30 packs per box (Cards per pack: To be announced by official sources)
• 42 card types, with a total of 137 regular card variations
• Rarities include rare, parallel rare, secret
• Top-tier pulls: Limited hand-drawn sketch cards and on-card signed cards

Buy a Box or Buy Packs? Purchasing Decisions

• Aiming for a complete set of regular cards: 137 variations mean different versions of the same card type, making it challenging to complete a master set. Opening boxes will be more efficient than buying loose packs.
• Hoping for a sketch/signed card: Artist hand-drawn sketch cards are one of the most sought-after categories in the art card market in recent years, but the pull rates have not been officially announced, so budget flexibility is advised.
• Just want to try it out: Buying loose packs to get a feel for it and collecting cards of your favorite characters first is the lowest entry barrier.
• Beware of unofficial channels: With Hong Kong as the first launch location and limited card types, market information will be chaotic during the initial release. It is recommended to only trust official distribution networks and familiar local stores.

Where to Buy in Hong Kong? Release Date and Channels

Official confirmation states an August 2026 launch with Hong Kong as the first launch location, but the exact release date, pricing, and list of Hong Kong retailers have not yet been announced. MOONROAD will continue to track release information and update our IG and online store as soon as news becomes available. You can:
