Greetings from Turkey, there isn't many shops that send gunpla to here. I got really surprised to see BanzaiHobby sending here. My package came in perfect condition and faster than i expected. Thanks for the great service
Banzai Hobby.. my go-to place for range and selection of RC parts from most major manufactures. Shipped with no fuss to NZ packed well and in a timely manner... Excellent customer service and prompt replies to e-mails..
Just plain 5 star every day...

I ordered some Kato ballast from Banzai, very pleased with the product and also the quick delivery.
First time buying on Banzai and I love it !!
Large inventory, affordable fast shipping to US. My order arrived in 6 days after placed.
Will order more often from now on.
Absolutely pleased with my purchase. Great quality, relatively fast shipping (considering the country where I live), and outstanding customer service. I highly recommended.
