Velour covers for foam building blocks RIWI

Why velor covers?

Some of our customers are public institutions, day-care centers and schools. The conditions are different and the stakes are tough. That's why protective covers were invented. Velor is just right because you can still build well with the now heavier building blocks (keyword: friction). Another positive effect is that the building blocks with a velor cover are very cuddly.

deformed RIWI blocks after unpacking

My RIWI building blocks are crushed after unpacking.

Due to the compressed storage in the packaging, the foam needs time to find its original shape again. Depending on humidity, temperature and storage time, this process can take up to 72 hours.

Usually this is done in less than 20 minutes after unpacking.

If you don't want to wait that long, you can use steam (e.g. from an iron) to speed up this process. -> Here is a video of it
