Safe-T Meter Stick and Inch Ruler

Description
This hollow white plastic instrument has paper scales. One side has a 39-inch ruler, divided to 1/8" along the top and to 1/2" along the bottom. Alternate pairs of half-inches are colored orange on the bottom scale. The interior of this side has a recycling symbol around the number 7. The rule is marked: P.O. BOX 692 La Grange, IL 60525 SAFE-T RULERTM.
The other side is a meter stick, divided along the top to millimeters and along the bottom to centimeters. Alternate centimeters are colored blue on the bottom scale. The rule is marked: SAFE-TTM METER STICK. According to the donor, this meter stick is designed so that the straight edge is at some distance from the chalk or dry erase board.
Safe-T Products, Inc., was established in the northwest Chicago suburbs in 1992 to manufacture and sell drawing instruments that were safe for children. Thus, the plastic of this instrument is shatter-resistant. It sold for $12.95 in 2000. For company history, see 2000.0160.04.
