Approximately 4.5 x 3.5" At isiko, we not only want our heartfelt, handmade products to look good, we want them to do good. As a social good company, every 6 months we identify a deserving organization and donate five percent of our proceeds to support their efforts. By shopping with isiko, you are also doing your part in helping those underserved communities. Your support and participation means so much to me, I simply cannot thank you all enough. Together, we can make this world a better place for all.
