This puzzle is an expanded version of the Meanders Box. In the 
Meanders Box, the top plate slid along with the four side pieces. In the
 Dual Meanders Box, not only does the top plate slide, but the bottom 
plate also slides. This allows for a puzzle with a large number of moves
 without the need to increase the steps of the side pieces.
This
 puzzle can be configured to 4 different positions based on the 
orientation of the 2 plates, which move counts being 325, 367, 410, and 
506 moves. Comes configured in 506 move orientation out of the box. More
 info on orientation and move count here -

This
 is a must have puzzle for Juno collectors and any puzzlers who love 
maze burrs. Cherry on top - it has a box space inside with a nice prize 
to find!
Near mint conditions - solved once and then reset.
Optionally
 - I also have a spare base for the puzzle which had some loose joints 
so I was sent a replacement base. Base part is everything except the two
 maze plates and the inner prize of the puzzle. If needed, I can send 
along that spare base as well for your experimentation.
Stored in smoke-free humidity controlled environment.
Can combine with other puzzles of mine which are listed.
Payment
 via PayPal or Wise. PayPal has a lot of fees (FnF not possible), so 
Wise is preferred, but not mandatory,  and I can offer 5% discount if 
using Wise.
