Handy Collections is a term used to describe collections of items that are useful and convenient to have on hand. Kits, which is the four letter solution to the crossword, is one type of handy collection. Kits typically contain a variety of items that are related to a specific purpose or activity, such as a first aid kit, a tool kit, or a camping kit. Having these items conveniently packaged together in one kit can be very helpful for people who need to quickly access the items they need.
