Warning!!!

1. You don’t need to fully tighten the egg holder! Simply ensure the egg is securely locked in place—over-tightening can increase the risk of cracking the shell!

2. For small eggs, be sure to install the included support bracket; when not in use, you can reverse the bracket’s orientation for compact storage! Be sure to trim each of the four edges down to about 1 mm in length. Remember: “small eggs” require the support bracket, while “large eggs” should have the bracket removed—and never be installed backward!

Don’t overtighten the holder! Just check that the egg is secure—cranking it down too far can crack the shell.
For small eggs, clip in the support bracket. Pop it on backwards for neat storage when you’re done.

Materials to Prepare:

1. The only material you need to prepare is a 65 cm–long core‑sheath nylon cord with a diameter of 1.5–2.0 mm. I personally use a 1.5 mm core‑sheath, non‑stretch nylon line—but if you’re using a 0.8–1.0 mm diameter cord, we recommend doubling the strand by running two strands together.

   

2. This isn’t a mandatory accessory—but if you feel the shaft isn’t sufficiently secure, you can reinforce it by threading in an M3×40 screw. Both standard head types work perfectly.

Notes:

1. Some eggs have particularly thin shells—once you can see the top window clearly and the egg feels snug, you can stop tightening to avoid over‑compression.

2. On average, pulling the mechanism 25–50 times should suffice—adjust based on your personal preference and feel.

2. If the mechanism starts making excessive noise, be sure to apply more lubricant to reduce friction.

Instructions:

1. Some eggs have thin shells. Watch through the top window—once snug, stop tightening to avoid cracking.
2. Pull approximately 25–50 times; adjust to your preferred feel.
3. If the noise is too loud, add more grease.
