PF102001 Magnetic Stapler, Plastic/Metal, White, 10.5 x 7 x 4.5 cm

It's a cute little stapler. Most older USA-made standard office staples are truly 1/4" tall and the staples I tried to use measured 6.43mm tall on my caliper. There's a pair of tiny guide tabs under which the stick of staples must pass inside the stapler's magazine. Problem is the clearance under the guide tabs is only 6.40mm. i was able to VERY VERY SLIGHTLY bend both guide tabs up enough for the US-made staples to pass under them using needle nosed pliers. You only need a couple thousandths of an inch additional clearance so don't bend them much at all. I later found a box of staples from "Staples" (a store in the US) that measured 6.0 mm tall - these are advertised as 6.35mm on their box - and they fit the stapler with no modification needed.

Tried using regular staples and wasn't sure they fit correctly. So I ordered some smaller ones. Waiting on those to come in
