Minifig display cases available at Amazon.co.uk
These minifig display cases have been 'hard to find' in the UK until now, partly because they are not available from shop.LEGO.com.
Amazon is now stocking them, and has them at 15% below RRP. At the moment only the yellow one is available in both 16- and 8-minifig sizes but it appears that black, red and blue in both sizes will be available in June, and can be pre-ordered now. (Thanks Renegade007cjh for the news)
