Each pack contains 7 pieces 10" long x 2 1/4" wide. This is made from 36 gauge aluminum sheet stock, slightly thicker than a soft drink can. Each pack covers a little over 157 sq. inches that's a 12" x 13" area. This material is easily cut with scissors or score with a hobby knife & snap off. This will give all your O & G Scale buildings that realistic metal roof. Each pack will be shipped in a reusable 3" x 12" zip lock bag. Contact me with any questions.
