The new Costco toilet paper rolls are larger in diameter because they are not wound as tight as were the old ones. The new TP certainly is double-ply, but the individual plys are thinner than Target toilet paper (which I now buy instead of Costco). Is rather disappointing that Costco would put their name on a product which is so scrimpy and lacking quality. And they still call it – have on the packaging – “PREMIUM”! I’d expect to get such underwhelming-quality TP at the Dollar Store or somewhere similar – not Costco.
