I’ve seen variations of these at my local Dollar Tree. The ones I saw had an H-shape but pretty much had the same guts. While it was tempting, I opted not to bother.
The tin metal reminds me of a tin can, especially with the folded over lip…would not attempt a thumb grind with this as it looks like it could be a nice finger slice! (We know how cheap items and quality control get along).
Off topic somewhat: My first ever full-sized yoyo was a Ja-Ru imperial-shaped yoyo. The string was wedged between the axle and the yoyo half, rendering it impossible to sleep. 2 days later I was a the mall and spent the money on a real Duncan Imperial where I learned in minutes how to actually throw and make it sleep. This was back in 1996.
