Join the Bungu Experience

Shopping from the Bungu store was super easy. After I learned about a product I wanted, I had it ordered quick & easy. It shipped pretty quickly, despite Silver week in Japan, and arrived without issue. Their packaging is such a nice touch! I almost didn't want to unwrap it. I enjoyed the entire experience and will order from Bungu again!

I am so impressed by the care and attention Bungun uses in their shipping. I ordered several inexpensive KOKUYO notebooks which came wrapped in a beautiful furoshiki. What an absolute treat. The special edition post card adhered to the bottom of the package was also such a nice, and yet unexpected, gift which went immediately into my planner. Honestly, opening the box was as much a pleasure as using the products inside. Thank you so much for your dedication to this level of customer service, I believe you truly stand alone.

I have bought from Bungu on six different occasions, and I have loved the experience every time! The website is great, and the support (if you ever need them or have questions) is incredibly quick, helpful, and polite. Order turnaround is highly efficient, and my packages always arrive at the earlier end of their delivery estimates. The furoshiki is beautiful, and the postcards are delightful. I couldn't recommend Bungu highly enough.

I've been a fan of Bungu's Instagram channel for ages, but this was my first time buying from them. I loved the experience. The shipping was surprisingly reasonably priced. The books came wrapped in a beautiful cloth furoshiki (with a little card and QR code explaining how to use furoshiki), along with a bonus greeting card tucked away in the bottom of the box as a delightful surprise.

I found out about the writing utensils from a YouTube influencer about two months ago who seemed impressed with the quality of their products and this company. I am a longtime subscriber so feel comfortable with their recommendations. Bungu's website is easy to navigate and understand, as is their ordering system. The delivery was timely. The packaging was lovely.
