For ER32 collets I have created this neat organizer/holder for your toolbox or workbench. No more sorting thru all your collets in a jar to find the right one. Comes disassembled. SuperGlue or other glue to bond acrylic will work fine. Comes with a protective paper applied. remove one side of each piece, glue together and when dry remove the second side.

Holds eight collets.
