RAK Magnetic Wristband
When you're doing a home DIY project and you're up on a ladder or crawling through some small space, one of the more annoying little things to deal with is keeping track of all those bits and bobs — the screws, nails, nuts and bolts, drill bits, washers, etc. But if you've got the RAK magnetic wristband on, it becomes a lot less of a pain.
It's got 10 strong magnets embedded nearly all the way around, essentially acting like a third hand that won't lose any of those small items when you need them most. I bought my dad something like it years ago as a gift, and he'll attest that this sort of thing is super handy to have on almost any job.
The RAK magnetic wristband is $13 on Amazon and is adjustable to fit most wrist sizes.
