Walnut Hollow Clock Movements

Class Packs — These economical quartz movements save money on projects yet ensure accuracy. Each class pack contains enough materials to make 12 clocks, ideal for classroom, camp, or occupational therapy settings. One AA battery (not included) for each clock is required for operation. The class packs include the following materials:

• Clock movements with 3/4", 3/8", or 1/4" shafts
• Hands (hour, minute, and sweep)
• Instructions
