3Racing bag and Team Magic's (for 1/10) are pretty similar
Different size boxes (3Racing 2 large boxes, 2 small boxes half height and width, TM 1 large box, 4 small boxes same height half width compared to large box)
Two pockets for 3racing on sides of the bag while TM has one
Tools on top both fit 10, but 3racing has them different positioned them
The front thing (sorry don't know the word) with the zip, when you "open" the bag you can secure it on 3R
I think those are the differences
I have them both and I like them.
One more advantage if you choose any of the above bags and you happen to you own a Mazda MX-5 (Miata, Eunos) the bag fits PERFECTLY in your truck
