I use these to display my table chips.
Lucite front & back - Pretty much air tight when front
and back are secured - You can view chips on both sides
Large rectangular holds 52 chips. The spade I use for the
metal tokens ....
Got them at Gamblers Supply on Main Street - Las Vegas
Also available thru their on-line store

There is also a heart and diamond available (red) - I chose
to stay with just black ....
