Its light and fits lots of things. I have been to competitions and it fits timers mats and many many puzzles

The SpeedStacks Bad is light and high quality. It can easily fit my timer in there as well as some of my puzzles. Overall, it is a great buy if you want to take your timer and cubes to competitions without damaging them.

This bag is almost like the bag from Mary Poppins! I carries about 8-10 cubes, or carry a folded up mat and timer as well. The bag is comfortable to hold and walk with.

Great for storing you Stack-mat with timer. Or just taking your cubes somewhere!
