Its exactly as it should be, support music shops and not e-bay folks
Very useful indeed. I used to oil the action using a sewing needle dipped in a spot of mineral oil - what a faff that was! The superslick is much quicker to use. Suggest you gently squeeze/prime the need before you bring it to the instrument (to avoid applying too much oil). The top screws off, so you can refil it with suitable lubricating oil.
