Luxury Brands just came out with a couple of ink wells to get every last drop from your ink bottles. Both are now available
Ink Miser Intra-bottle Inkwell
This inkwell was specifically designed to fit inside a Noodlers bottle of ink but can also work on other bottles such as Monteverde or Platinum. With the inkwell inside the pen you can rotate the bottle and catch the ink inside the inkwell making it easier to fill your pens when the ink get low.
Ink Miser Ink-shot Inkwell
The ink-shot is designed to transfer ink from your ink bottles making it easier and safer to fill.
