Using the TBS Caipirinha II decal sticker set is a breeze. First, clean the EPP skin of your Caipirinha II where you want to apply the stickers to ensure there's no dust or debris. Then, carefully peel off the sticker from the backing paper and gently place it on the desired spot. Smooth it out with your fingers to get rid of any air bubbles. When it comes to maintenance, keep your model away from sharp objects that could scratch the stickers. If the stickers get dirty, you can gently wipe them with a soft, damp cloth. Just be careful not to use any harsh chemicals as they might damage the vinyl.
