Using your AC/DC gift set is easy. Just pour your favorite hot or cold beverage into the mug and place it on the coaster to protect your surfaces. The keyring can be used to keep your keys organized and show off your love for AC/DC. When it comes to cleaning, wash the mug and coaster with mild soap and warm water, then dry them thoroughly. For the keyring, a gentle wipe with a damp cloth should do the trick. Avoid using abrasive cleaners or scrubbers to prevent damage to the logo and designs on the products.
