Bandai 1/144 Option Parts Set Gunpla 10 (Galaxy Booster)

Galaxy Booster: the 12-wing backpack from Build Strike Galaxy Cosmos, as an option parts set

Bandai's Option Parts Set Gunpla 10 turns the Galaxy Booster, the backpack of the Build Strike Galaxy Cosmos from Gundam Build Fighters, into a stand-alone set. Each of its 12 wings moves independently, so you can shape a wide range of silhouettes, and it comes with joint parts so it can be fitted to other Gunpla.

What makes this set special

  • 12 independent wings: each wing moves on its own, so the booster can go from a tight profile to a wide spread.
  • Striker Pack system: Bandai says it lets you equip the booster on a variety of Gunpla.
  • Joint parts included: one set of joint parts to widen the range of customisation.
  • Display pedestal: a pedestal is included so the booster can be shown on its own.

What's in the box

  • Galaxy Booster x1
  • Joint parts x1 set
  • Pedestal x1
  • Sticker sheet x1

Compatible kits

Frequently Asked Questions

What makes these Gunpla kits the hottest sellers?

These kits are fan favourites for their detailed design, affordability, and build size, offering a balanced and enjoyable building experience.

Are these hottest seller kits suitable for beginners?

Absolutely! Especially the HG kits, which are known for their fewer parts and simplicity, making them a great starting point for new builders.

What is the level of detail in the MG and RG hottest sellers?

MG kits boast a detailed inner frame and additional parts, while RG combines MG’s complexity with HG’s size for an intricate, compact build.

Can I get replacement parts if I lose some during the build?

Yes, if you buy a kit from Mecha Express Australia we will source replacement parts for you. This is not a quick process as parts need to come from Bandai in Japan.

How much space will I need to display these Gunpla?

HG and RG Gundam kits are compact, while MG Gundam are larger but still manageable. You won’t need too much space to showcase these masterpieces beautifully.

Amazing Build, my Grandson loved it!

I purchased this kit and one other for my grandsons birthday. He loved building it and found it easy to follow. My order arrived in super fast time and was beautifully packed. It even had some wonderful freebies in the box which was really great. Excellent product and service in every way!

Great selection of kit, excellent value for money

Awesome kit, great extras. Only criticism is that the kit comes with a base so you don't need the second one. The kit also doesn't have the ability to take the blue LED bonus so if you don't have another use for it it is wasted. Luckily, I'm a Gundam tragic so will always have uses for extra bases and lighting kits.

Excellent service and fast delivery

I purchased on 6 Jan and my order arrived on 13 Jan. It was very well packed, with both boxes in excellent condition. Cam even provided a small free gift in the box! Overall purchasing experience was smooth and hassle-free. I haven’t had the chance to build the kit yet, but based on the service and care taken with shipping, I would happily purchase from this store if there are other Space Battleship Yamato models available.

Very rare with fair price

If you were one of the lucky ones that were able to travel to Sydney Gundam Base pop-up in 2025 and queued extremely early (like the first 40 or so) on the first day, probably you were able to grab one of these. Otherwise, the only alternative I would know of is traveling to Japan and being uber lucky of having it still being sold at Gundam bases. Otherwise, it's a second-hand market, and prices will go up. That said, the price was fair, I think it would be similar price as using a dropship service from Japan, with the exception that it's much faster and way more guaranteed you will get proper merchandise. So, Mecha Express, Cam, thank you so much for your store!
