Moving house is always a massive undertaking, especially when it comes to packing all your possessions into boxes. Books in particular can pose a big challenge as they're heavy and most of us have a lot of them filling our bookshelves.
If you pack books into a cardboard box, there's a good chance the box will break unless it's reinforced. Plus, a box of books is quite heavy to carry, especially if you're moving a lot of them.
Instead, pack books into wheeled suitcases. The suitcases are strong and won't fall apart like a cardboard box, plus the wheels make them easy to move around.
The best option is to use a suitcase with four wheels, as they're easier to move, especially when full.
