good plan on finding a canadian supplier - Wish I'd been smart enough to do that, lol. I ordered 3 sanituffs from the states and got bent over by UPS for the shipping. although I do have an extra unwrapped 1/2x12x18 if you want.
they do tend to bend every now in then, but if you put 'em on the counter warm right out of the dishwasher, they straighten right out.
