how many uses do you get for each piece of chalk? Do they last like 20 uses or 10?

It depends on how long your hair is and how much of it you use. I think it'll be good for well over 30 uses, but it's just for little section highlights.

I didn't really use them..it was a mess and hard to get a good color on my hair but I also didn't like any other hair chalk so it could just be me-however they were pretty thick I think they would last more than 20 uses depending how much of it you use each time

They last quite awhile if unopened. I use them at least twice a day which seems reasonable (at least to me) for someone who is not taking a full shower and uses a toilet or alternative at least twice a day. A package of 8 cloths does not last me that long.

The chalk comes off with wiping of any kind. I have not washed my jars yet. I imagine if you put them on a clean jar they would stay on for a while.

I get at LEAST 2 YEARS of usage from mine, before they then begin to tear a couple of inches from each of their ends, during the type of back-scrubbing motions as exhibited on their packages' front. If you don't routinely scrub your back in this manner, I'd imagine they would last you at least FOUR years. (By the way, once they do become shorter from their ends tearing off, I THEN use the "spent," smaller cloth for pot-scrubbing, shower-stall or sink cleaning, etc., for a few MORE years of usage).

What do you plan to use them for? Using them for hands on play only lasted us 3 or 4 days then they were breaking easily in our hands, however, we only used a very small portion of the bag so we have plenty more to make other days.

How long are you expecting them to last? For me, I sharpen about 6-10 pencils before the fine blade dulls. I can replace it twice (with the replacements provided) and the threads seem to hold up. The actual sharpener body is aluminum, I think, so you can overtighten the screws and screw up (HA!) the threads.

I used them in Cvaults. Typically they last a few months. It also depends on how dry or wet the material is. Another factor is how often the container is opened.

You might as well just buy more. Re-using these isn't really worth the effort. And then you'll always have those old designs saved for layer anyway. Also, since they're just cheaper plastic, I would imagine that they would start breaking down after a while if you did use them that way.

I dont know how Long they are. But it's worth it. I have many rolls and I know they will last for more than a year. I use them once per week.

I really don't know but it's not worth buying. They may last 3-5 times after use. And I think I'm being generous by saying up to 5 times.

they last several uses I still use mine occasionally and they still stick. I've had mine about a year

Because you can reuse them it depends on how you clean them off. I would buy the large set but no more then two just in case a tattoo breaks or gets overly saturated and can't be used. I'd say at least 5 times per tattoo. Make sure you put them back on the white paper

You can remove them whit a little work , and no residue ,just dont use chalk if they are going in cups because the hands erase what ever you write on them

It's a little hard to say how long they last, But i feel I get a lot out of them because I do quite a bit of printing for both black & white and color. They seem to last quite long. I hope this helps.

It comes with a piece of soapstone to write with. It'll wear down quickly, so I'll switch to chalk

OK, I just measured -- with calipers! The piece of chalk I have in there right now is 0.370" diam. It looks like that is the standard school-chalkboard-chalk size. (Nominal diam 0.375") And the length is 3.25" or so when the chalk is new. But! As the chalk gets used up, how short can the piece get before you have to throw it away and reload? I just tested that, too. The gadget can still grip the chalk securely when it is only 0.5" long, and you can still use the stub at that size. So it's going to waste very little -- less than you would if you were hand-holding the chalk. OK, I just measured -- with calipers! The piece of chalk I have in there right now is 0.370" diam.

They are not easy to use. And like the size of old school chalk (if you are old enough to know what a chalk board is lol) hope this helps
