Thank you for viewing from among many items (*^^*) Rabbit Resin Empty Frame Frame With Crimp Charm Set of 2 Large size. The yellow one (probably Alice in Wonderland white rabbit) is about 5mm thick. You can use it as a key holder or bag charm as is, without using resin ☆ Since it is made overseas, there may be some unevenness in the plating. Please consider this before purchasing. Shipping will be done using the cheapest method. Please understand that items may be deleted suddenly m(__)m Thank you. I also have other handmade materials for sale(^^)
