*plain, non-salt* crackers/snacks ? (Jakarta)

Hi there,

I have found that here in Indonesia luckily I can get various and inexpensive snacks/crackers/biscuits! :)
But still... as I eat normally very plain (don't really need to put any spice), most of crackers are added salt/sugar or spices... I've tried already some and it is for me somehow pretty salty.

If there is someone who know or found already a //non-salt (or even low-salt) cracker or snack// please recommend some (name/store). :D

Cheers,
Hyemin
