I couldn't take the picture. It will not show that clearly.
There are tiny bumps. dust under the silk screen. Looks like when they do the silk screen, there are some dust on the canvas. Not that noticable. just the side of bag have different canvas with the main body. Main body have no that problem.
for example when you polished your nails, if you didn't do it well, it will have bumps on your nail, if you have some dusts on your nail, you didn't wipe it, and you polished your nail ,it will show the nail is rough not smooth. hope this can explain better.
