The grip sleeve should be included with the original purchase just like the stand and the first set of blades.
The razor handle is completely smooth and it makes it easy to slip from your grip when shaving in the shower. The sleeve is an elegant solution.
The grip does not go on like in the pictures.
The lack of knurling on the SE makes it slippery and easy to drop if you're a bit clumsy and you shave in the shower as I often do to save time. The sleeve is the cure.
Makes every shave more comfortable every time with the grip sleeve on my new supply razor
I never thought I had an issue with grip on the supply razor, but once adding this, it was night and day on the level of comfort in holding it.
Simple yet great solution!
