Avery - AVE41413 Keep track of all your children's gear using these brightly colored Durable Labels for Kids Gear. They're perfect for labeling daycare, school and camping gear, lunchbox items, sippy cups, bottles, sporting goods and electronic devices. Water-resistant labels are dishwasher-safe and microwave-safe and stick to plastic, wood, metal, rubber, paper, ceramic and glass. TrueBlock Technology allows you to completely cover up whatever is underneath the label. The labels are handwrite only and work best when using a permanent marker. Each sheet includes four rectangular labels (3-1/2" x 1-1/4"), and labels come with borders in green or blue.
