801 Glue is filled with pure original glue, which leads to better results and higher strength. It is not the diluted 502 glue found on the market. Although the price is higher, it is worth the cost. The glue is suitable for metals, stones, wood, bamboo, ceramics, and rubber. It is not suitable for PP/PE/silicone plastic. If you are unsure of the effect, please contact the customer service to recommend the appropriate glue. All glue has a shelf life, please purchase in the right amount. If it solidifies, it cannot be exchanged or returned. Please use it with caution, and do not use it on the human body or for human use. It should be placed where children cannot reach. Due to the filling process, there may be an error of 1 to 3 grams in the glue. The glue does not have an independent packaging.
