Lustre Polishes - 
Cosmic Shimmer have several products that come in this style of jar - Lustre, Opal, Metallic & Glitter Kiss - please click through and read what the difference is between each product - the Jar however stays the same - we have a brilliant glass base with plastic lid, on the top of the lid we have a built in applicator that you can just pop out. 
Maintenance with all of these products -  When you have finished using the product, spritz a couple of pumps of water in the product and on to the applicator before storing - this will prevent the product and the sponge drying out. 
Lustre Polish -  Is a pearlesk product that is chocked full of flakes of mica... when you use the applicator to cover your card stock you will see a very fine, almost glittery finish!
