Avery - AVE61505 Rectangular labels feature a special adhesive that's engineered to stick strong and remove cleanly from smooth hard surfaces including metal, plastic and glass. Durable, professional-grade material resists water, chemicals and abrasion, and provides superior bar-code scanning. They are great for use in warehouses, offices, factories, hospitality and more. The removable adhesive sticks securely but removes cleanly for easy, on-demand changes. Labels are simple to customize with text, graphics or bar codes using the free online software from Avery Design & Print. They are recommended for indoor use. Labels are not recommended for use on walls. Sheets are compatible with both laser and inkjet printers. Each sheet includes two labels.
