No. I did not make the silicone grease. But it is in an absolutely adorable container with a cute little sticker, which makes it perfect for popping in your pen maintenance kit, your pen case, your bag, whatever. It's also useful for things other than O-rings on pens. O-rings and section threads are where you'll put a tiny amount of this bad boy, especially for eyedroppers. It also helps with squeaky bits!
Try not to let it melt because it can be gross and sticky, and make sure not to get any on your nib and feed unit. Or in it.
