The following is information on the regular 13-hold pack:
The Educational Pack consists of the 13 most common climbing grips. These holds teach climbing terminology. Each rock climbing training hold has its type engraved into its surface, so every time a beginner climber grabs a sloper, crimp, edge, pocket, etc., they'll learn the terminology. This is an excellent set to use as an introduction route during belay certifications and intro classes. They are also a perfect choice for schools.
