I bought these after a lot of searching for something that'd work well to hold my colored pencil set so that I can easily select from them. The hole size is perfect for standard pencils and there's enough space between the holes that they're easy to grab. Plastic feels dense and sturdy, so I'm pleased with the quality. I've also tried the side with bigger holes and they fit Faber-castell PITT markers and standard size sharpies perfectly.
