Radius offers models for very young children and for older kids/teens. Examples in the listing include toddler sizes starting around 18 months and options aimed at older children or teens (around 12 years and up). Availability varies by specific model.
Handle materials include plastic and beechwood (some listings note polyester components). Some handles are described as 100% recyclable, while others are labeled biodegradable/compostable — typically the handle only (excluding the brush head). Check the specific product listing for exact material and end-of-life guidance.
Some Radius toothbrushes list an overall length of about 7 inches. Travel or mini sizes are also offered for certain toddler and compact models — check the product description for the exact length and availability of a travel/mini version.
Radius toothbrushes are sold as single brushes and in multi-packs. Examples in the listings include 1-count and 3-count packages; other pack sizes may be available depending on the product.
Radius designs include easy-grip handles for toddlers, an octagonal handle shape intended to encourage proper brushing angles, and ergonomically comfortable wooden handles noted by reviewers. These features aim to make holding the brush and maintaining correct brushing technique easier.
