These are 2 little, flat boxes for hiding geocaches. The bigger box is 85 x 85 x 8.2 mm (plus hook). The drawer is held in the box by 2 neodym magnets 5x5x3mm and 2 wood screws 2x12mm (Spax). A fitting logbook can be downloaded here.

The smaller box is 63 x 65 x 6 mm (plus hook). The drawer also uses 2 neodym magnets 5x5x3mm and 2 nails 1,4x25mm to stay in place. A fitting logbook can be downloaded here.

In addition you will have to glue the top to the case. I normally use UHU Allplast or UHU plast special for this purpose. Please beware those boxes are not waterproof of course.

Update: As I had issues keeping the log book dry in the other boxes - my cache is exposed to full wheather, I design and uploaded a flat, round box, that so far proofed to be almost rain proof.
