★ Handmade Head and Finger Exercises: Cap Puzzle - 42 pieces on one side, 84 pieces total with both sides, using the "sanzui" radical (氵) ★ The front side has white caps, and the back side has colored caps. ★ Everything is handmade, starting from making the round stickers, drawing lines on colored paper to select the characters, writing the characters on the stickers, and then attaching them to the caps. ★ Because the characters are different on the front and back, even with one sheet of colored paper, there are 84 puzzles to solve, making it a rewarding experience. 〈I apologize.〉 ★ There was a mistake in writing one character; I wrote "me" (メ) instead of the "ki" (汽) for "steam engine" and corrected it with correction tape. ★ Since everything is handmade, there may be some areas that are difficult to see, but I would appreciate your understanding. ★ Flipping over each cap to see it is also a stimulation for your fingertips, and it's also a brain exercise, so how about it? ★ You might consider using it in places where people gather (such as children's groups or senior citizen's clubs). ★ The price includes shipping, and the shipping days are set for a longer period, but I want to deliver it as soon as possible, so thank you for your understanding. ★ I would like you to purchase with the understanding that there are no returns. Thank you. 〈Bonus Hint Present〉 I made an arrangement using the 84-piece puzzle caps, so please use it as a hint and try making your own. Thank you.
