About 20 squares, might have a couple more when I look further. There’s some conne tors, maybe not enough for all the grids, some are chipped or need cleaning (I used some for a Guinea pig enclosure) but they are available to buy separately.
The grids are sometimes used for really nice Guinea pig indoor enclosures (c and c homes)
Also versatile, use for all sorts
Hackney E8 1JS
Grid storage squares (c and c?) (E8 Hackney Central)
