Fellow collectors...If you're looking for small dimension display cases, you should pay a visit to the RM5 shop
Daiso Japan located at
LG308e, One Utama Shopping Centre (new wing). If you're coming up the escalator from the
Reebok store, it's only your left, right at the end near
Cold Storage.
This store has approximately 200,000 items for consumers of all ages. Don't expect electronic wares in here, but you'll find a myriad of useful wares, tools,
receptacles, toys and even Japanese snacks and munchies.
These plastic display cases are found on the second last aisle from the back of the store near the other plastic ware and opposite the gardening section.

The one shown here is a
69 x 69 x 59mm (Width x Depth X Height) plastic display case with my
Star Trek:TNG comm badge in it. This gives me incentive to bid for a screen-used comm badge going on eBay now. :)

Next, we have a
8.7 x 9.3 x 9.3 cm display case with a flat base. Ideal for porcelain figurines and 1:64 scale die cast cars. I house my
2008 Hallmark Star Trek: The Wrath of Khan diorama Ornament which makes a snug fit. Now it's free of dust and actually enhances the "dramatic" moment of the USS Reliant ambush on the bridge of the Enterprise..."on screen Mr.
Sulu..."

This one has the same dimensions as the former, save as it comes with
2-semi circular mounts on the base designed to raise flat items to give it some character like this
TNG Type 1 hand Phaser.

The other variant I purchased is a
21 x 7 x 8cm plastic case in which my T
ype II hand Phaser rests. In fact, the fit is so perfect, the
phaser hardly jostles when I move it around. This variant has somewhat a
octagonal design which frankly, I think they could do without but instead have smoothen, rounded corners. I think the design was deliberate to make these versions for stacking as depicted by the pictogram on the packaging instructions. I can't have my cake and eat it too...
One thing to bear in mind though, there is
no refund policy. I suggest visual checking your merchandise before checking out.
