Teka-teki Saku Delta

I've had mine on my desk for a week and still haven't managed to snap all three triangular pieces back together without a fight. That little catch it makes mid-slide is oddly satisfying though, and it's the perfect fidget for when I'm on hold.

The way it pulls apart in three directions at once is so clever—my brain didn’t expect that catch halfway through. I’ve been fidgeting with it on my desk all week and it still surprises me every few tries.

I was skeptical a puzzle this small could be so tricky, but that moment where the three triangular pieces catch and refuse to separate keeps me coming back. It fits in my palm perfectly for desk fidgeting, and I've already lost track of time twice today.
