TEC

I can't respond in any way related to your request as I follow orders given. TEC is a line of pieces for toys creation. The pieces can be freely joined, beyond the possibility of joining them with other products, like recyclable packages. The idea is to encourage the reuse of objects to fabricate new toys.
