These colored dot labels are designed with a brown flexible paper. This allows the object to be clearly visible while being less conspicuous than the preprinted items. The colored dot labels have a permanent adhesive backing that will help the object stick to any surface. The ability to stick so well will make the item reliable since the adhesive will not allow the sticker to fall off. Additionally, the item has a 3/4" diameter that makes the item fit onto any kitchen container.
