The playpen for small animals is made of plastic slats. Each park is composed of 6 plastic sheets that give it an exagonal shape. But since it is a modular structure, you can join as many sheets as you want.
The lower part of the park is closed to avoid direct air currents, since there are small animals such as chicks, which would be negatively affected by these currents.
The plastic sheets are joined with plastic tabs, with the possibility of making two heights thanks to the fastener reference 329G.
