I just fell in love with these!
Each link in this cleverly designed ruler measures one inch.
Made of durable plastic, it can be laid flat, wrapped around an object, or folded into a cube for compact portability!
When completely folded together, it measures only 1.5"" x 1.5"" x 1"". Fully opened it is 12" by 1.5".
Measurements are given in both inches & centimeters.
