An aglet is the plastic or metal tip at the end of a shoelace. Lace Lab Silver Bullet Metal Aglets are 20 mm silver metal tips with a classic rounded bullet shape for sneakers and most standard laces. Each pack includes 4 bullet-style metal aglets and 1 super glue. Is this the right add-on? The bullet shape gives laces a high-end, heavy-duty look. No anchor screws are needed. To install, put two to three drops of the Lace Lab Super Glue into the aglet, slide it onto the lace tip, and hold pressure for a few seconds. Go easy with the glue so it stays inside the tip. The inside diameter is 3.9 mm, so these suit most flat and standard sneaker laces. For a slimmer look, see Silver Cylinder Aglets.
