As an Industrial and Scientific buyer, I was hoping for better results .Through trial and error I found that these biscuits and plugs were difficult to use and prone to breaking. The size and shape were inconsistent, making it a hassle to find the right fit. However, the price was somewhat reasonable and the packaging was decent. Overall, I would not recommend this product for anyone looking for reliable and easy-to-use biscuits and plugs in their industrial hardware projects..
