i was actually looking for ratchet belts (i think thats what there called) but i can only find ugly ones online. bought 1 before when i was overseas and lost it the next day

To describe it the ratchet belt it locks like a cable tie but has a release button when you want to take it off. Well if anyone knows where to get them in sydney thatl be awesome. best leather belt ive come across so far
