Based on our own experience these biscuits are the perfect fit for all industrial and scientific furniture. The plastic insert is flexible and sturdy, which makes it highly durable for long-term use. The insertion process is also very easy and hassle-free, making the whole process streamlined. However, we wish the packet had included more number of biscuits. Overall, we highly recommend these biscuits for all your furniture needs in the industrial hardware category....See full review
