<<...I have forgotten where Steve S suggested using hard felt nibs...>> ...It may have been Post #19 in this discussion thread; the relevant content was: "...Got the trusty micrometer out this afternoon and made a few measurements: <> Bamboo Feel white Hard Plastic nib: 0.0632" <> Bamboo Feel black Rubber-Tip (?) nib: 0.0625" <> Surface Pro blue Hard Plastic nib: 0.0625" <> Wacom black Hard Felt nib: 0.0690" <> Wacom gray Stroke (spring) nib: 0.0675" <> Wacom white Hard Plastic nib: 0.0690" So the older, "traditional" Wacom nibs are significantly larger in diameter than the newer, "Feel" style nibs; this means that the traditional nibs will not fit the new Feel pens (also the Surface Pro pen). The good news here is that the Bamboo Feel nibs fit the Surface Pro pen and so in addition to replacement hard plastic nibs, you also have the alternate choice of the rubber-tipped Feel nibs. I'm test driving one now in my Pro pen, and on the Incipio Screen Protector, the feel is pretty nice..." <<...they were the Bamboo Feel IT nibs that would fit the Surface Pen. Is that right?..>> ...As noted above, that is correct. <<...is Wacom the place to get them, or would another vendor be preferable?..>> ...Good question! I would normally go to the OEM for replacement parts, but Wacom seems to be unusually flaky about keeping their nibs in stock. The current URL for nibs at the Wacom store is https://us-store.wacom.com/Catalog/Accessories/nibs and, in particular, the "soft" Feel IT nibs (ACK20603 in black) appear to be at https://us-store.wacom.com/Catalog/Accessories/Nibs/Soft-Nibs-for-Bamboo-Stylus-feel-black , which would be great except that they show "Out of Stock!" And, unfortunately, this is not uncommon for Wacom. Note that a version in white is also available (ACK20604). AND... if that weren't frustrating enough, Wacom's "Bamboo" naming convention, which they apply to several products that are mutually incompatible, makes it really difficult to determine exactly which nib you need to order! So, my advice is to keep an eye on the Wacom store in the hope that the nibs come back into stock before global warming gets us all. In the meantime, check retail sites like Amazon and auction sites like eBay to see if the nibs may be available there... And good luck!
