#3 If someone know a site that we can all order the necessary material, can you give it to me because I don't like to order on different site!
It would be really nice to order everything at the same spot, but unfortunately this is not possible.
#4 When they say that we need 5 pack, we can see that they are 5 objects in the pack so do they want that we buy 5 packs of 5 (25) or one pack of 5 (5)
one pack of 5 (you can usually guess this by the price)
does it enough long and big to place all the things that i need to put?
yeap it should be big enough. there are other bigger ones you can get too. i recommend finding a larger one.
