Super handy little bottles
I only *needed* one of these empty Sailor 20ml bottles, but I got five, because you never know when you're going to need an empty one! The one I was in immediate need of was to split an ink my roommate and I bought together. It was easy to wash empty bottle out, and then I just used an eyedropper to transfer half of the ink from one bottle to the now clean empty bottle and tah-dah! Two bottles of ink! These actually hold 23-25ml of ink comfortably, or at least the one I used to hold half of a 50ml bottle of Diamine Blue Edition Polar Glow did, and I assume they're all the same size.
In addition to ink, I'm sure these bottles would be great for other uses as well. The glass is crystal clear and thick, especially on the bottom, which really gives it a steady, weighted base. The other thing I really like about these bottles is that they are squared off. They fit very neatly with each other (and make a very pleasing clink sound when they bump up next to each other), and while they're not the same size, they fit nicely with other bottles with corners as well, like Monteverde's 30ml bottles. It certainly makes your inks look very nice and tidy! I'll definitely be back for more if I find I need more than the remaining 4 I now have haha.
