I'm often asked what type of magnet I use in my mini album and where I purchase them from.
The magnets I've been using are rare earth neodymium magnets that measure about 1/3 inches across and 1/32 inches thick. Just search "rare earth magnets 1mm x 8mm" on Ebay to find suppliers. Quantities and prices vary.
I usually buy them from China as they have the most reasonable prices and offer free shipping. But it takes about a month to receive them here in Canada so I order bulk quantities to make sure I always have some on hand.
I'm still on the lookout for a supplier who offers larger magnets at a reasonable price.
