Tente was a line of construction toys created in 1972 by EXIN-LINES BROS S.A., a plastics and toy company based in Barcelona, Spain which ceased operation in 1993. Subsequently, the trademark and patents were acquired by EDUCA BORRAS, and as of 2008 the toy line appears to be discontinued. Their later series were no longer compatible with the old system, although some models remained compatible. The toys consisted of multi-colored interlocking plastic bricks in multiple scales and an accompanying array of wheels, minifigures, and various accessories.
