Our 47 repositionable wall decals provide colorful, subtle support for Mandarin Chinese language learners in the home. Our decals, each 2.5" diameter, highlight the Traditional Chinese characters for common household items and room names. Each prominently features the Chinese character with a colorful image of the object being identified. We showcase pin yin on every decals in small subtle font so that the learners eye is initially drawn to the Chinese characters. Decals are printed on 4 sheets of white 3 mil vinyl. These wall decals like to be adhered to smooth, clean surfaces. Before applying a decal to a chosen location, use a warm damp cloth to wipe down the surface and let it dry completely. DO NOT use soap or cleaning agents which may impact that stickers stickiness.
