These are Galaga Sprite badges, which I have created using Perler Beads (melted plastic beads). Here is (from left to right) the Bee, the Galaga, and the Butterfly. The Damaged Galaga will be available as soon as I get dark purple beads.
I am selling these badges for wear at this year's Megaplex: Retro Arcade! $5 for the Galaga, and $3 for the Bee and the Butterfly. This is available for preorder, which will be delivered to Megaplex. If you are not able to attend, add $2, and I'll mail it to you in the US. Payments by Paypal is most prefered.
