The Japanese tend to buy a single school bag for their children for the entirety of their school life. This means that they are built for comfort whatever the wearers size as well as practicality. 
This bag has been designed with these ideals in mind. I am happy to guarantee the leather on these bags for 10 years. Available in a wide range of colours (N.B. If you choose the option in the White circle, you WILL NOT RECEIVE WHITE, this option is for a multicoloured bag. Please specifiy which colours you would like. Each individual piece will be made in a different colour)
 
Please be aware that this is not a traditional Randoseru rucksack, it has the added bonus of also being able to function as a satchel. I have developed a method of adapting the strap so that it can be worn either way. 
This model has a quote from Firefly on it, but you can have your own quote or motto or whatever on yours. You could even have it as a blank canvas for your own artistic talents. 
 
Totally Kawaii and great for school or to complete that cosplay outfit. I can also add a smaller pocket under the flap of the bag for phones, small tablets etc. for a small additional cost
