TouchMatic Eraser Refills

I got an e-mail notice from JetPens the other day that the E-Knock erasers were back in stock. I ordered some refills and 1 complete eraser, in blue. They arrived Saturday. Upon inspection I discovered that the E-Knock and the TouchMatic were almost identical twins. The only real difference (besides one being transparent and the other opaque) was that the push button end caps were different. The end cap on the TouchMatic is solid while the end cap on the E-Knock has 4 vents in the top. It also locks in with a snap. The TouchMatic's is held in by friction. The push buttons and nozzles are however interchangeable.

So, after all these years, I now have a source for refills for my beloved TouchMatic. Way to go Mitsubishi and JetPens.
