A popular shoulder bag now comes in a flapless model!
From the classic shoulder bags that have sold over 200,000 units domestically, the flapless model has finally arrived!!
"I want a shoulder bag that can hold my essentials securely!"
"I'm looking for a shoulder bag that matches any outfit!"
Are you someone who usually looks for everyday bags or backpacks with such concerns?
There are surprisingly many items you want to carry on your days off, such as a long wallet, smartphone, PET bottle, handkerchief, and folding umbrella.
These essentials can be stored comfortably and are lightweight.
And it’s a versatile shoulder bag that matches any outfit.
For weekends and commuting to school or work
The biggest feature of BLUE SINCERE's shoulder bags is, without a doubt, their large capacity.
They can hold big items like long wallets, PET bottles, and folding umbrellas, which tend to take up space inside the bag.
Additionally, with a total of eight pockets of various sizes, you can organize and store items like smartphones and card cases separately.
You won’t lose track of things inside the bag and can quickly take out what you need.
For overnight trips or casual outings
If you usually carry little luggage, you can comfortably go on day trips or overnight stays with items like underwear and toothbrush sets.
It’s also very useful as a secondary bag for overseas travel. Please take a BLUE SINCERE shoulder bag with you on your trip.
For a new way of working
With the progress of work style reforms, many people now commute in casual clothes.
It can store not only tablets but also notebooks in B6 or A5 sizes, making it useful for reading or replying to emails during transit.
What is BLUE SINCERE?
With the philosophy of "developing the brand while solving social issues in Bangladesh," we produce bags and wallets in our own factory with Bangladeshi artisans, exploring the potential of local materials, and creating high-functionality products that are competitive even in developed countries.
