2 x Aluminum Alloy Chalk Holder Teacher's Chalk Clip Clutch (Mixed)

This is a simple, light-weight, easy to use chalk chuck. There's not much to the mechanism - just two tubes (one inside another) with a spring in between them. The inner tube has the jaws that hold the chalk, which expand when the back is pushed. This simplicity of design ensures that there's not much that could go wrong with the chuck.It accommodates an entire piece of chalk with a little room to spare on the inside (i.e. when the chalk is fully retracted, it doesn't come into contact with anything on the outside). If you push the back and hold the chuck vertically with the tip pointing down, the chalk slides out (the chalk slides out under gravity; you have to be careful or it will fall out and break). Likewise, if you push the back and hold it vertically with the tip pointing up, the chalk retracts under gravity.It holds even the tiniest pieces of chalk with absolute firmness. I used a 1/8th inch piece of chalk on this thing until the jaws were touching the board! Absolutely no wastage!The only downside is that if you're not using chalk of the diameter that this chuck was designed for, it's totally useless (the simplicity doesn't ensure room for fiddling and making various chalk sizes fit).Very elegant, very simple, not expensive at all! What more can a teacher ask for? Go for it... this one's bang on the buck!Edit: Forgot to mention; this one's meant for a 9mm diameter chalk. I think (although I'm not sure) that there are various products being sold under different names (like Charles Leonard, School Smart etc.) but they're all actually identical to this one in appearance.

Overall, the product is very useful for the price. Aside from the occasional slipping of the chalk within the case, these chalk holders have done well to keep my hands and clothes clean and write more smoothly on chalkboards!

They work just fine, but I wouldn’t let young kids use them. Nothing is made to last these days and these are no exception, but will work fine as long as you don’t mess with the prongs. My kids got jnto the chalk and used the edges instead of the tips, bc that’s fun and I don’t mind it for art projects, but once a little bit is worn off the sides of the chalk, it no longer has the thickness required to stay snuggly inside the prongs and will just push into the holder when you go to write. If you try to squeeze the prongs tighter, as you might guess, both chalk and the prongs will collapse into the holder as the small catch keeping the prongs from going too far in are now smaller than the opening of the holder- just common sense stuff. But again, just use with care and should last a good while.

Perfect. Keeps the one year old from breaking the chalk, and curbs her interest to eat the chalk. I would recommend.

Not very good as a mechanical holder, the "also bought with" has crayola chalk, snug fit but no way to let chalk out without fussing with it. Just keep in mind, chalk will not come out without a fight, might as well use chalk by itself.

For the quick arrival and design was great for the costume unless your looking for a detailed item, this was great by those that didn’t pay close atten. Loved it!

The idea of having a device to hold chalk so it does not get all over my hands is nice in theory. I purchased these holders confident that they would be like the ones I remember from my childhood. Unfortunately, like so many other things, the quality is somewhat lacking. This device will not hold the chalk in place at all. Even the slightest pressure applied while writing will cause it to sink down into the holder. I have tried adjusting the "arms" and the spring tension without any improvement. I have also used 3 different brands of chalk with the same outcome. I consider this purchase a total waste of time and money.

Funny how a little addition like these chalk holders can make your life easier but they do! Minimizes breakage of your chalk and provides an easy fit in your hands to make writing with chalk on boards easier.
