Many kits bundle extras like multicolor pens and matching sticker sheets. Some diaries add novelty features such as light-up covers, invisible-ink pens and padlocks; memory books commonly include guided prompts, section tabs, decorative sticker sheets and a back pocket for keepsakes.
Sizes vary by design. Typical examples include butterfly stickers around 1.5 x 2.1 inches, leaf stickers about 2.6 x 1.5 inches, and alphabet/letter pieces roughly 1 x 0.5 inches.
Stickers are used to decorate water bottles, mugs, phones, laptops, mirrors, notebooks, scrapbooks, planners, photo albums, calendars, cards and gift wrap. Journals serve as diaries and memory books, and are also used for planning (weekly calendars, checklists), tracking appointments or medical notes, and storing photos or keepsakes.
Most items target young children and are commonly labeled for ages 6 and up, with some products listing narrower ranges such as 6–8 years. Check the product listing or packaging for the manufacturer's recommended age range before purchasing.
