Some time back I needed to generate numbers between 1 and 100. I did this by getting a die which was numbered 1 to 0, twice. This was painted with one set of 10 being in red, representing units of ten, and the other sides left plain. Therefore a red 2 = 12, a red 8= 18 if plain it would be 2 and 8. Today I was looking to find similar shaped dice….. and could find one anywhere in the UK. Can anyone suggest who might have them?

Are those called "percentile dice"? If you can't find them, you could go with different colors of d20 (or d10), or get the big d100.

Sounds like the percentilke dice. As Bill says, you can also use two different coloured d10's to achieve the same result, simply nom inate which colour dice is the tens, and the other is the 110. Suggest Doug at Em4 might be able to help in the UK.

I got some 20 sided die numbered 1 0 from EM4 in white, red, and black, I believe he has them in six different colours.

They make various 10 sided dice to use as percentile dice, if desired: 1 – 10 0 – 9 As well as 10, 20, 30, etc……….. to 00 (which can be read as zero zero [or zero], or as 100). Pair the tens die with one of the other D10s for your two dice, D100 combo. I really love D20s too.

D20s are a staple of Dungeons and Dragons. Any shop (online or brick and mortar) that sells D&D supplies should have some.

… the thing is that I am looking to throw 4 dice at a time to generate 4 numbers between 1 and 100. This is why using two dice 10 don't work as i would need to know which die went with which dice to make the 4 numbers (if yoy see what i mean). It is also why most percentile die wouldn't work marked in tens but not units. The 20 sided 09 die is perfect (once half of it is painted) and I have just managed to find a supplier, thanks.

So do you want 4 numbers between 1 and 100 ? Or the 4 numbers between 1 and 20 that you would get from your 4 painted 20sided dice ?

Just get percentile dice sets which are a tens die marked 00,10,20..90 and the other a D10 marked 110. Get 4 pairs in 4 different colors. Then yes, you throw 8 dice not 4, but the red tens die goes with the red D10 and the blue tens die goes with the blue D10 etc.

"So do you want 4 numbers between 1 and 100 " Yes "Just get percentile dice sets which are a tens die marked 00,10,20..90 and the other a D10 marked 110. Get 4 pairs in 4 different colors." Marked 09 would be better(saves counting the 10 as a zero) ?

"… D10 marked 110. Get 4 pairs in 4 different colors."Marked 09 would be better(saves counting the 10 as a zero) ? Those are out there. I have some in polyhedral dice sets that I probably acquired in the 80s or 90s. But the most commonly available D10s nowadays are numbered 110, for use as a standalone D10. For the many games that use D10s (D20 system / D&D, and White Wolf Storyteller, are two). Pairing with the tens die from a standard dice set lets it also serve as the ones place in a percentile pair. 
Dagwood  18 Aug 2019 11:57 a.m. PST 
Chessex do 10 sided dice marked 00 to 90 (percentile dice), and also D10s marked 0 to 9. Lots of colours, so you can use pairs of the same colour. The bad news is that they are £1.00 GBP each, so 4 pairs for £8.00 GBP The way prices seem to work they could well be $1 USD each in the US, so $8 USD for a set of 8, else perhaps $10 USD for the set. Plus postage, of course. Probably cheaper ones available from China, unless the tariffs have been raised !

Or get 4 D100 dice. I bought one and rolled it years ago, still rolling to this day I think.
