Backyard X-Scapes Bamboo Poles Size: 1" D x 8' H; 25 Piece Bundle

Are these treated with any chemicals?

What are people using the 8 foot, 1 inch diameter stakes for? I assume they will be strong enough to support tomato plants?

Can i get these in 12 ft lengths?

i really wanted to dance my "tinikling". Do you think this product works for it? one of my biggest regret before my parents forced me to migrate to US
