Steady hands, tiny holes, zero ruined pieces
You know how hard it is to drill a tiny hole without ruining the piece.
One slip and eight months of saving that project idea is gone.
That grip moves the control from your wrist to your fingertips — the same fingers that have written neatly your whole life.
Shells, beads, wood, resin. Clean holes, first try.
One of our most reordered craft tools this season
✓ Drill beads without holding your breath
The pen shape rests between your fingers, so small movements stay small. No wrist swing, no sudden bite into the material.
✓ One tool for 4 craft materials
Works on shells, wood, resin, and soft metal. Drill, sand, polish, and engrave without swapping to a bigger machine.
✓ Brass collet grips bits tight, no wobble
The metal collet holds standard 3.0mm bits square and steady. That's what keeps your line straight and your hole round.
✓ Light enough for long sessions
Slim aluminum body you can hold for an hour. Your hand won't cramp halfway through the fun part.

Frequently asked questions
Can I use it on glass or stone?
Yes, with the right bit and a slow, steady pass. Let the tool do the work instead of pressing down — pressure is what cracks brittle material.
Do I need to buy special bits?
No. It takes standard 3.0mm shank bits, so you can pick up extras almost anywhere craft or hardware supplies are sold.
Is it loud enough to bother people in the same room?
It runs quieter than a full-size rotary tool. Most people describe it as a soft hum, not a whine.
Will it stall if I push too hard?
Push too hard and it will slow down — that's by design. Ease off and let the bit cut, and it keeps a steady speed.
How to use
- Step 1: Charge by USB before the first use. Give it a full charge so speed stays even.
- Step 2: Loosen the collet, slide in the bit, and tighten by hand until snug. A loose bit is what causes wobble.
- Step 3: Hold it like a pen and rest your hand on the table. Let the bit touch the material with almost no pressure.
- Step 4: Move slowly and let the tool cut. One or two light passes beat one hard push every time.

Does the denim paneling feel stiff to wear?
No. The panels are placed at the neckline, lapels and sleeves to hold structure, not across the body. The parts that touch you most are soft ribbed knit.
Can I wear this as my actual jacket in fall?
Yes, in mild to cool weather. It's a substantial knit layer, so think crisp fall days over a tank or tee rather than deep winter.
Will the knit stretch out at the elbows and hem?
The ribbed construction is built to spring back, and the denim panels take the stress at the sleeves and edges. Hang it rather than folding it to help it keep its shape.
Does it close in the front?
It's designed as an open-front layer. That's what lets the denim lapels frame the outfit underneath.
- Size: Length 27.5–30 in; sleeve length 22–23.5 in (see size chart tab for full measurements)
- Material: Soft ribbed cotton-blend knit with denim panel detailing
- Available in: 8 colorways
- Machine wash cold with similar colors
- Do not bleach
- Hang dry to keep the knit's shape
