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

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.

I bought this because I like carrying a piece of chalk with me when I'm working on stuff. Chalk is great for making marks on surfaces like wood, steel plate, etc. It's also cheap, and usually easier to find than soapstone or paint markers (which always seem to dry out on me). I like carrying chalk but I hate fishing broken bits of chalk out of my pocket when I inevitably bump into something. These holders were actually cheaper to buy than a single holder of a different design. The reviews were mixed but for the price I decided to risk it. I'm glad I did. So far all I've done is to load chalk in them, but they feel solid and hold the chalk very securely. Pressing on the top of the holder causes the fingers that hold the stick of chalk to loosen so that you can feed some more out or load in a fresh piece. If you've ever used a mechanical pencil, the mechanism is similar. I'm not in love with the anodizing on the holders-- the colors look a little washed out to me-- but let's be honest here: For the price, these are an absolute bargain. They're thicker than a Sharpie but shorter, and they drop into a pocket pretty unobtrusively. The build quality looks good so I'm hoping they stand up to a little garage work. Time will tell.

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.

Item is good. But I asked the Amazon AI which chalk was compatible with it and it gave me Kedudes Dustless Chalk with Eraser, 24pk. This chalk did not fit.

Does not hold chalk in place. Chalk continually breaks and when I apply pressure (that is, to write on a board) the chalk either breaks or sinks back into the holder making the produce unusable.

Never put chalk in it, might be fine for that. But as an Imperial Code Cylinder it is just okay for limited use. I have found that the clip does not hold the prop in place for very long. Also the color at the top is wrong, but I knew that when I got it. It's good enough for a few trips out in the world if your not trying to be 100% compliant.

Good deal used for a costume prop

Not ashamed to admit I bought these to serve as Imperial officer "code cylinders" for my Director Krennic costume, a purpose for which they excel. It was that or buy $100 replicas. No brainer.

カッコ良さに惹かれ 買ったはいいが 内径が細く 日本の標準的なチョークは 使えません。 良く調べない 自分も悪いが目立つとこに 表記してくれよと 言いたい 9.5mm用と…

Just as pictured and just what I was looking for! Personally I'm using this as a prop for a costume and not for it's intended purpose so I can't vouch for it's ability to hold chalk but I'm happy with it.

Perfect little gifts, it was well received!

These holders are completely metal...the cheaper ones in stores have a plastic lining that falls apart...these last and last...great value

径が小さく、チョークが入らない。全く購入した意味がなかった。
