Great for kids!

Went to visit my grandkids (age 8 to 15). They get bored quickly with everything so decided to try some puzzles. These were great. Kept them occupied for hours. Thanks.

Really cool puzzle

But my son cracked it in less than 10 mins! I love that they can keep solving it over and over. Though we know how it’s done now, we race to see who was fastest in solving

Decent, but..

Ordered what I expected, nothing incredibly hard, but just something small for entertainment. My only 2 things are.1) The string for the bag was unraveling already on opening, so it can't be used without a replacement string (I used a shoelace for string durability and its easier to string through the bag holes)2) No directions incase for some reason anyone gets stuck on these puzzles (they shouldn't, but still, it would just be helpful overall for reference, incase one if the puzzles are damaged or bent/not working as intended)Otherwise they are fine.
