Art and craft supplies, which I guess technically falls under ‘tools’ the the first post on here suggests.

Although obviously paper, plaster, cement (for tile mosaics and the like) and air-dry clay or Model Magic are single-use items and things like markers, pencils, crayons, oil pastels, chalk, paints, glue, etc. are all consumable items and will be used up over time and need to be replenished, but still.

Also, some way to mitigate any inevitable messes from using this type of thing on-premises will need to be hatched out as art and crafts are varying levels of a messy endeavor to get into, especially once the glitter or chalk/charcoal or plaster comes out or once you get into things like paper mache and such, or even when the clay comes out especially once pottery wheels are involved, or when you get into things like making slime.

Ooh, maybe even host a community sidewalk art or tile mosaic stepping stone day, that would be awesome.
