There is one design in this set. The hold duplicates five times to make up a set. They are exact mirror images of each other so if you are looking to build a head-to-head Lexan speed wall or Hanging Ninja Panels as seen in the thumbnail images, you are good to go.
This set is an excellent choice for ramped rubber soft play installs as its round contours are gentle on the children's hands and feet. For more variety, check out the 10 Pack-2 Bolt.
