Spoon size: 9cm long, 3cm wide The keychain uses a ball chain. Made with silicone sealant, there may be a noticeable odor. If any parts come off, please reattach them with glue. I have a cat. I made this in a room where the cat isn't allowed, so I don't think there will be much cat hair on the product itself, but there is a possibility. I will remove any visible dust before shipping, but some may still get attached. Please refrain from purchasing if you are looking for a perfect product. Instant purchase is OK. #UsasanWhipDeco Whip Deco Spoon White Donut
