One or more aspects of the present disclosure provide optical element transfer structures that include an optical element releasably coupled with a transfer medium and methods of making and using the optical element transfer structures. The optical element transfer structures can be used to dispose an optical element onto an article, whereby the optical element imparts a structural color to the article.

Interactive therapeutic devices for wear on a head of a user are provided herein, along with kits including the interactive therapeutic device and an activity book, and methods of using the devices and kits. Contemplated devices comprise a set of attachment points that removably couple with a set of patches via fastener components. The patches can include various types of patches that provide different benefits to the wearer, including style, a scent, a noise, a tactile sensation, protection, and/or the ability to better communicate a feeling and/or a need.

A cap includes a head cover and a bill extending from the head cover. The head cover is configured to be worn on the head of a user of the cap. The bill includes an inner wall that defines a vent through the bill. The cap may also include a mesh located in or across the vent and configured to allow airflow through the vent. In some embodiments, the vent may have a shape that imparts information to a view of the bill of the cap.

The hat flag comprises a flag mount and a replaceable flag assembly. The flag mount may be coupled to a hat and may present a threaded receiver for detachably coupling the replaceable flag assembly to the top of the hat. The replaceable flag assembly may display a flag elevated above the hat via a flag support rod when the replaceable flag assembly is detachably coupled to the flag mount. The replaceable flag assembly may comprise a spring-loaded base such that the flag support rod may tilt when an external force is applied and may right itself when the external force is removed. The replaceable flag assembly may comprise a bearing such that the flag is free to swivel.
