Ruby B. ★★★★★

Even with a bit of CA glue, I had no trouble centering these on the tube. Nice that they're molded as one piece so alignment is consistent, and the plastic is rigid enough to hold up to ejection charges.

Claire ★★★★★

Slid right onto my 25mm tube with a perfect snug fit, no sanding needed. The one-piece molding is clean and straight, made my rocket look sharp on the pad.

Lily ★★★★★

The injection molded plastic is surprisingly rigid for its weight, and it fit my rocket tube perfectly without any sanding needed.
