Bhai durability ko lekar main khud abhi sure nahi hoon although ye pulses wale bag kaafi strong hote hain par paudhon ke liye use karna matlab sunlight, mitti aur paani se everyday contact hoga toh ho bhi sakta hai ki ise har saal badalna pade PAR, 1 rupay ka bag hai aur roughly 1 hour ka time laga ise banane mein to agar change karna bhi pada to mujhe nahi lagta isse koi fark padega. :)
