Shuttle has a deeper eraser well so cut them 1/2inch. also have Bic mechanical pencils, these fit just a titch tight but work, Bic's eraser wells are smaller so may only need to cut 3/8 inch . So ar I like how these work. will buy again.

Hard to find size. Fits my mechanical pencil perfectly

These erasers work much better than what comes with our mechanical pencils. Would highly recommend.

I am an architect. I began back when we didn’t have computers or AutoCAD. So it was all about line quality, hand lettering, etc. Pencils & pen quality were important. These days computers are what are needed. All of those quality pencils & pens were no longer needed but are excellent for those of us who are also artists. I still use all of my old mechanical pencils. I simply replace refills. Or get new pencils. Mr Pen is now my “go to” for those supplies. Same goes for the pen style eraser I have. It’s amazing, is not a modern click style; it’s a plastic pencil length tube for refill erasers. It has a topper that twists off to insert the the eraser refill. You then move the eraser up to the level you want to use it and then tighten the topper again. It’s more easily controlled, has a better grip than the newer click erasers. But the width/diameter of the eraser refills are not equal to the eraser refills used now. Why tell all of this? Well, as I’m a huge fan of Mr Pen, I saw that these were available for a good price. The detailed info stated the diameter was 1/4”. Which is what the older eraser refills for my architectural pencil eraser is. The regular ones are too small in diameter And will fall out of the pencil erasers. So I need a 1/4” or a little more. But, when I tried using these I saw they won’t fit & aren’t a true 1/4” diameter. Otherwise, they erase very well. No smears, smudges or other issues. I’ll still be using these, just not on the item I bought them to use on.The search continues.

These fit the common BIC 0.8mm mechanical pencils where BIC does not offer replacement eraser refills for. They're easy to cut to size.

Did not work as advertised.

My daughter only uses the Bic 0.7mm HB #2 mechanical pencils. The problem is we are constantly throwing them out because there are no eraser refills Bic sells. We buy refill lead for them, but once the eraser goes we are S.O.L.So I checked Reddit for some answers and finally someone posted a link to Amazon for ones that work for these mechanical pencils. And sure enough they fit nice and snug. They are pretty much long erasers that you can cut accordingly. My first picture is all the mechanical pencils that would have been thrown out again if weren't for this product. The second picture is a comparison between the old Bic eraser that is well used and this product side by side. I only used a kitchen knife(pictured) to cut small 1cm pieces to fit in the pencils.I hope this product will last awhile on here, but just in case I purchased 3 in total. These will save our sanity and I think some money.

Perfect size and erases well. Also used with other pencils but trimming one of the erasers. Great quality for price.
