Setting Stats on Magic Items [3.5]

[Cieyrin]

I thought that items with extradimensional spaces simply become inaccessible in anti-magic.

Gloves of Storing don't have extradimensional spaces, they shrink the item to a speck in the palm of the glove.

The item is held in stasis and shrunk down so small within the palm of the glove that it cannot be seen.

So an antimagic field would make it regrow to normal size.
