Clean, tight wraps in 60 seconds. EWrapper hand wrap roller

EWrapper rolls your used combat-sports hand wraps back into a tight cylinder. About a minute per wrap instead of three by hand, and they stop tangling with everything else in your kit bag.

EWrapper is a hand wrap machine: a motorised spool in a 3D-printed box, running off a 9V battery.

Sht 02 — How it works

Three steps, every time.

After training, unwrap as normal. Then:

i.

Hook the thumb loop

Drop the wrap's thumb loop over the spool. That's the only setup: no threading, no tension to dial in.

ii.

Close the lid

A magnet pulls the lid shut. A small switch confirms it's closed before the motor will run, so wraps can't escape mid-roll.

iii.

Switch on and guide

Flick the switch and lightly guide the wrap with one hand so it doesn't fold over itself. About 60 seconds later, press the spring-loaded ejector and a clean, tight cylinder pops out.

Sht 03 — Why

Tidy wraps. Less faff.

ProblemHand wraps come off damp and twisted, and they need rolling back into a cylinder or they tangle with everything else in your kit bag. Doing that tightly by hand takes around three minutes per pair, and it still comes out lumpy.
ApproachA motorised spool inside a closed housing. Drop the thumb loop on, shut the lid, flick the switch, guide it lightly. The motor does the winding at consistent tension; the spring-loaded ejector pops out a clean cylinder.
ResultAbout 60 seconds per wrap, ~3× faster than by hand. The cylinder comes out tight and even. Pair them, drop them in your bag, done.

  1. 1Magnet: pulls the lid closed so wraps can't escape mid-roll.
  2. 2Lid: opens to load the thumb loop, closes magnetically to start.
  3. 3Motor and spool: winds the wrap at consistent tension.

Sht 06 — How it compares

EWrapper vs rolling by hand.

Aspect EWrapper Rolling by hand
Time per wrap~1 minute~3 minutes
FinishClean, tight cylinderOften lumpy, depends on patience
TightnessConsistent (the motor sets tension)Varies wrap to wrap
EffortHook + close + flick + guideManual technique each time
Cost£29 (one-off)Free

EWrapper wins if you train often enough that two minutes of rolling per pair adds up, or if you care what your kit bag looks like. Hand-rolling wins if you train occasionally and don't mind a lumpy bundle.

Sht 07 — Frequently asked questions

Quick answers about EWrapper.

What does EWrapper actually do?
It rolls a used hand wrap back into a tight cylinder for storage between sessions. It does not put the wrap on your hand: you still do that yourself. EWrapper deals with the mess afterwards.
How long does it take?
About 60 seconds per wrap. By hand it takes roughly three minutes.
How is it operated?
Hook the wrap's thumb loop on the spool, close the magnetic lid, flick the switch, and lightly guide the wrap so it doesn't fold over itself. When it's done, the spring-loaded ejector pops the cylinder out.
What sports is it for?
Boxing, Muay Thai and MMA. Anything with a standard combat-sports hand wrap that has a thumb loop.
How is it powered?
A removable 9V battery, accessed through a dedicated door at the back. No charging cables, no proprietary battery.
How much does it cost?
£29 GBP. Out of stock at the moment. Use the form below and I'll email you when it's back.
Where does EWrapper ship from?
United Kingdom, with free UK delivery. I do ship internationally: email contact@ewanwills.co.uk for a quote.
Is it machine-washable?
No. The wraps are washable, the EWrapper isn't: it's a 3D-printed unit with a motor inside. Wipe it down between sessions.
