I found this on budgetdreamwedding.com
One place i could think of these spice jar is IKEA. I dont remember how much they sell the jar but googling online, 4 pcs is for Rm16. That means Rm4 each..pretty pricey for a gift..but it could be a cute deco at the candy buffet..
ps: nak guna as candy jar agak kecil. Tapi di IKEA ada jual transparent jar yang besar. nanti check price...
