storage problems

[silky43]

over the years my gemstone collection has been steadily growing in size and I am being faced with the problem of how to house it economically and compactly. the obvious decision for me is to use the circular acrylic containers that fill any shops that sell this type of thing. this is my favourite choice and I am wondering if anyone knows where I can get some for a cheap price, possibly in a case. in bulk is ok if it is below 300 units.
thanks in advance for any help

They are everywhere. I buy often on ebay and from Rio Grande. Or, if you are near a gem show, they typically have a great selection there as well.
