Reply to Small Vinyl Letter or Alphabet Stickers For Vestax VCI Mod

I'm having a very hard time finding letter stickers (black and preferably vinyl stickers) that are small enough to fit on the backlit led buttons of my VCI-300.

At first I thought about writing on them with a permanent marker, but that will ruin them for ever I'm affraid (Iin case I ever would resell the unit again).

I believe I now have finally reached a mapping that I will stick with for a time to come. I know what all the functions of all the buttons are, but I believe it would be a bit more clear and intuitive if I also could read it off the backlit LED buttons.

It's a pain in the *ss to find the stickers. The maximum height of the letters can be no more than 5mm.

Anyone got some place or shop I can turn to? I live in the Netherlands, so an online shop woulld be preferable.
