I am sure that the product I am familiar with is of the highest (Chinese) standards. A red tube, accompanied by the brand name Primera, along with 5 stars and the assurance in English that it is "First Quality". It reminds me of the glue that was once included within the kit used to patch my bicycle tires as a youth. Little needle top as well to puncture the opening. Usually sold in strips similar to disposable razors for the ease of sale in the colmado. To be used with madera, goma, plastico, papel, metalico and piel or shall I say wood, rubber, plastic, paper, metal and leather.
