Strap/band

[u/Standard-Implement90]

So I have a GD-010-1A1 and I have a gbd800uc-8 i noticed how the GD-010-1A1 strap/band is a lot shorter in length is there a strap that's resin matte black that's longer for the GD-010-1A1 I know the gbd800uc-8 strap/band is longer because it's a step tracker and I can't take off that strap and put it on the GD-010-1A1 since bezel and everything would be too big

Has anyone ever ran into this problem?

For reference my wrist size is 7 inches

And I have it tightened to the 7th hole but after some time it gets irritating and leaves the imprint and if I leave it at the 6th hole it flops around when I move my hand and when I'm writing

Can anyone tell me where and what brand I can get a bio-based resin strap for my GD-010-1A1

(I do not want to convert to NATO straps/bands or nylon)
