Hi! And welcome to Glider Central!
I wonder if Indonesia has other types of wheels available. This reminds me a lot of a woddent wheel. I personally won't use them.
Do you happen to have a closer picture? Maybe a picture of it attached to a cage to see how much clearance there is between the wheel and cage wall?
One other thing is it has an axle or bar in the middle. Gliders like to jump in a wheel more than run. The bar keeps them from jumping.
This one will need to be cleaned daily as they potty and poo as they run too. It will eventually smell bad and get sticky and the center bar or axel could catch their patagium.
If you look at the wheels here:

I hope this was helpful.
