Thermwell B2 90-Ft. Gray Mortite Weatherstrip Caulking Cord - Quantity 10

if it seems too good to be true, it probably is. This product offering is for 10 rolls of caulking cord for just under $18 delivered. What was sent and what arrived was 1 roll of caulking cord. In addition, this Mortite was manufactured in China. In my experience, the rolls from China are noticeably inferior to the rolls manufactured in the USA. The inferior cord does not adhere to the surface and over a short period of time will fall off. Expect to get what you pay for- which is about $6 a roll and made in the USA, not $18 a roll and made in China..
