ABSTRACT:
A scale for weighing light items, such as letters, to ascertain the correct amount of postage to be applied to the letters. The scale includes a substantially planar flexible strip having a proximate and distal end. The proximate end includes a scale calibrated in weight units, while the distal end includes a vertical resilient strip for holding a letter formed by cutting an inverted U-shaped slot in the strip and a horizontal slot. The proximate end of the strip including the scale is bent back upon itself and passed through the horizontal slot. The distal end can then move under the weight of the letter relative to the proximate end to indicate the weight of the letter on the scale.
