I am a school STEM teacher and was glad to find this multiple pack of 1-2-3 blocks. The quality of these is very good and the price was excellent. These came well packaged and were quick to put to use for my students in middle school and high school, helping them to use for assembling projects. These are virtually indestructible so they should last forever.

had to remove machine oil and wax. I know that was used to keep them from rusting so expected.
