About this sound
This is a just-under-four-second spoken clip of a voice delivering the Portuguese line 'Vem pra caixa voce tambem', inviting listeners to come to Caixa too. It feels welcoming and nostalgic, like a friendly call everyone is included in. The file tags name it as 1984 Caixa material.
