Age recommendations vary by product. Many Crayola scented items list 3 years and up; some product types list higher minimum ages such as 5 or 6 and up depending on the item.
The product listings describe scented marker lines as washable—specifically washable from skin and from most washable clothing. Some dual-ended marker descriptions also note the ink can wash from most painted walls.
Scented colored pencils are typically sold in 12-count packs and come pre-sharpened. Product descriptions note wood/wax construction, a listed point size of 3.3 mm, a No. 2 lead designation, and an age recommendation of 5 and up.
The scented modeling dough is sold as a 3-pack of 1 oz tubs (net wt. 3 oz / 84 g) in resealable containers. Listings indicate the product is intended for ages 3 and up.
Descriptions list fine tips, chisel tips (for producing both fine and broad lines), broad tips, and dual-ended markers that provide two tip types per marker.
