Purchasing these markers was a BIG mistake! When I went to remove the cap the writing portion of the marker pulled out with the cap. It was a struggle to separate it. They are not a good quality item. I’m very disappointed.
Very nice markers. Last long tip stays sufficiently sharp for the life of the marker. There are two concerns. First they aren't long enough to hold onto when the cap is off and secondly the cap doesn't stay on. Real nuisance when it goes bouncing under a desk or table. If they lengthened the marker by another inch and improved the cap they would be perfect.
They write on all surfaces they don't bleed they don't dry out they seem to last forever just an all around great marker. Also you can't beat the price.
