Dumbbell weights keep falling out? Here's your solution and at the best price. Complete custom replacement disk set for the series 1 handle (#2,3,4,5 in photos). (Dumbbell is shown in photo as an example and not included) Printed in PETG, in my opinion much more durable than the original disks that would crack and let the weighs fall out. Will add video of them in use. feel free to message me with any questions. I usually will respond within 12hrs, most of the time much sooner. Note: This is a set of 4x disks (one of each). example: 2x of this set would complete an entire handle.
