I haven't found what I'm looking for online, so I'm wondering if there is a specialist term for this type of dice that would give me better luck.
## What I'm seeking
I'm looking for dice that are identical to standard d6 dice (pips representing the numbers) except with only the faces 1 to 5 having pips. The 6th face is blank.
## Proof of existence
I know these exist, because they are the input resource for companies that print a customised 6th face. However, I haven't been able to find a source for the raw dice without any customisation (which presumably will be considerably cheaper).
## Terminology
Is there a name for this kind of dice, or a search term that will work better? So far I have tried terms such as "d6 blank 6th face", "zero-indexed d6", or "customisable d6". The nearest results have been either completely blank (no pips on any of the faces) or pips on 5 faces but uninked, so the pips are barely visible. Since I'm aiming to prototype with several hundred d6 dice, I'd like to avoid having to ink them myself if possible.
## Purpose
I'm working on a board game where each piece is a dice, and the number on the top face indicates which player controls that dice. A dice with 3 pips on top is controlled by player 3. All dice start out neutral, which in a 5 player game can be represented by showing 6 pips on top. The game would start with all dice showing 6, and then they would change to other numbers during the game, as players convert them.
It would be much easier to see where the neutral dice are if they showed blank faces instead of 6 pips. I'm open to other suggestions of how to make the neutral dice stand out, but all I can think of is printing a custom image, which is a more expensive option than simply having a blank face.
