Its a bag.  You fill it with chalk. It doesn't make children weep at the sight of it.  What more do you need?

Its a ball of chalk. A chalk filled ball. A sock that has been stuffed with chalk. In other words, if you're looking for a device that will administer chalk to your hands in a combirtsblrnergsnomic ball shape, then this is the thing you're looking for!

It's small enough to fit in a chalk bag if you're a climber like me. And the draw string is so much more preferable to those annoying stapled bags that just bust open.

4 stars for just one reason which I highlight below

Pros:
Its Rasta colored which is awesome
It can hold boat loads of chalk, I have plenty of chalk in it plus a full chalk ball
Its soft and big enough to put any hand in it easily
I have never seen anyone with the same chalk bag

Cons:
4 Stars because the latch that closes it is all jammed up after only having it for a month or two.
Like most chalk bags they get chalk but this one seems to absorb the chalk more because of the fabric
The top doesn't close all the way up but that is a common problem for most bags.

In the end its a great chalk bag, I love using it and if I could offer one suggestion, to keep chalk from going everywhere I would suggest putting whichever chalk bag you may purchase in a big plastic bag when transporting. I would update it to 5 stars if they were to fix the closing thing on the side but its a great product.

If you aren't afraid to get your hands chalky and dirty for your workouts, this is the stuff, would recommend putting them in a chalk bag

This chalk bag is great! Fits perfectly in my bag.. The quality of the chalk itself is also really good. Definitely would recommend it! Also, 321 Strong might be the nicest store/company I've done business with. Jeff Hollenbeck, the founder, seems to genuinely care about his clients, making sure they are happy with the purchase. Thanks, Jeff!

The bag is good but the chalk bags broke open very easily

Update: I was shipped new chalk balls along with a new bag after my other ones broke.
I am happy with their product and their service

The bag is filled with the crumbs of the food. It must have been shipped many times and gotten very rough handling for th ieces to have been smashed into crumbs. It's not usable.

Nice bag. Could be less expensive. He just started to take it to school. Don't know how strong it is yet. It's navy blue and black

The bag is made of a slightly rough, burlap like material. It is almost square shaped, while it appears elongated in the image. The emblem is printed on, time will tell how good a job was done. Still a decent bag, probably holds two or three sets of 7 piece polyhedral die.

It is a standard backpack made of heavy duty canvas.  No surprises.

Should you carry a laptop in it?  Probably not: there isn't padding.  It's a canvas bag.

Should you put a dog in it? Probably not: it isn't fashion conscious enough for you to look acceptably ridiculous.  It's a canvas bag.

Should you actually parachute with it? Probably not: while it looks like a parachute bag, its not.  It's a canvas bag.

Do you want to carry things on your back from point a to point b?  Then this is a good bag for you.  I have been using it recently for transporting gym goods: from knee braces to gym shorts, water bottles, yoga pads, whatever, if it can fit in a bag, this can carry it.  The material is thick and the seams are well stitched so it seems to be durable; after a month's use it is like new... except for that stain.  But that was my fault.

It's chalk. It's pretty hard to screw this up. My 3 & 6 year olds had no complaints.

It was a laptop bag...I had no idea!  it also has a pocket on the bottom for a ball.

The chalk bag itself is useable, good but nothing special. The big negative though is the waist cord. It is just a piece of nylon string that is not really useable at all. Paying more (or getting a different product) for one with a proper waist strap with clasp or buckle would definitely be worth it.

This is the best chalk, period.  It shouldn't be complicated to make chalk, as it should be 100% MgCO3, but for some reason, I find other chalks or rosin bags to contain other ingredients, and they tend to reduce friction, like talc.  Just get your own bag/container, and put this in.  Don't mess around with liquid chalk, rosin bags, refillable socks, etc; they are garbage.

Nice little chalk bag, its not too big, holds quite a bit of chalk. The drawstring works well, it hasn't spilled much chalk at all. I would recommend to anyone who wanted something modest and useful.

It is a plastic bag.  I tought was a paper bag.  I didn't like. The sticker is too small for the size of the bags.  The curly ties you have to do on your on.  I think should have more explanation on the web. Specialy should say is plastic bag. Should have more pictures just the bag empty so we know what we are buying.

Great. It changes its appearance according to the waste bag you use.
