Well kept's blade bank is the perfect place to safely store your used safety razor blades. Once full, you can send it back to well kept and they will recycle it for you and send you a new, empty blade bank! We often get questions about how to deal with old blades. While they are recyclable, due to how sharp they are, they cannot be recycled in your curb-side pickup. Scrap metal places are happy to take them, but this is obviously not the most convenient.... we’ve been working hard to solve this issue and finally have! The blade bank measurements are: 7.5 cm x 4.3 cm x 1.6 cm and it is made of stainless steel. Please ensure the box is, in fact, full before shipping it to us. Box should fit 80-100 blades.
