🔍 What’s the concept & what claims are made

These electric diamond pens use a micro vacuum suction mechanism instead of wax or putty to pick up and place the diamond drills/stones. The idea is:

• No sticky mess or having to “re-dab” wax/putty.

• More consistent pick-up (if suction strong enough).

• Possibly faster placement (less downtime switching / refreshing wax).

• Often cordless / rechargeable designs, quieter motors, replaceable tips.

For example, one model claims: ultra-strong suction lifting both square & round drills, one-touch switch, whisper-quiet < 35 dB, 800 mAh battery, USB‑C charging, etc. isuvio
Another model “Electric Diamond Painting Pen” mentions vacuum suction, ergonomic & lightweight design, 800 mAh battery in a kit with tips for round & square drills. Diamond Painting 24
