no idea as it come stored inside a plastic bag , label said tree bark, didn't molest it cos i have no use of it 
they also sell those mangrove wood very cheap , rm4.50 for a 15cm-20cm++ big chunk.
if i go again i will check for you. I take the assumption it is real tree bark wood cos it put beside the real mangrove wood and the label
didn't said artificial tree bark.

Ya, have to treat the real stuff. Scared have residents in there.
Then ur gourami commnuity became pupus. I'm looking for branches effect. But dont come cheap

thinking of 100% tearing down my 2ft.
But need to buy razor blade to decom the bracers.

Nilufar Pet & Aquatic in tesco jln kuchai lama selling real tree bark for rm8 each like your picture.
size quite big as well.

Update, my bad , pardon an oldman , those tree bark is sold by gram , 100gram for RM8 , i touched it, feel real but i'm not expert.
picture enclosed , each of those pack is like 400g , so 4 x RM8 = RM32 each.

Size is like 60cm height x 30cm ft width


And those cheap mangrove wood & stone on shelf, price range RM3 till RM30(big chunk) , i use those in my crayfish/vampire crab tank, so far so good.
Just need to boil and let it settle in a bucket for few days to leech out tannins.

I think you will like this place as this the only LFS i find lot of weird stuff like albino frog , firebelly newt , imported crayfish . army crab ,
primitive fish, etc , the only shortcoming is that they only carry few brand of aquarium accessory/products. No Eheim, No ADA , No Aquazonic
No Hailea , No Resun and.. 

Pls remember DON"T buy the RM1.50 Check Valve from there. it have fault , only let pass like 40% of air (like tersumbat).
