Ikea no longer lists a "GLIMMA" tea light holder on their Web site, nor did I see one in the store today. I did look on the Web first, and found the "GLASIG" instead.

It's a square base instead of round, so it doesn't blend as well with the Revomaze cylinder shape, for sure. That said, it's the same inside dimensions (duh, both made for the same thing), and the square base looks more substantial, and possibly more stable. I bought a pack of 5 for US$3.99 plus tax, and I think they do a great job storing your mazes upright.
As Prodigy noted, there's room at the bottom for pins (and spring if you are paranoid about removing it before allowing people to pick up and mess with a sleeve still containing that tiny part), and the sleeve and shaft rest very securely and attractively there.
