Frequently Asked Questions

check_box

What is it actually made of?

A heavyweight sherpa fleece and cotton blend. It’s thick, plush, and genuinely warm — not the thin scratchy material you get on cheap costume onesies. The hood, spikes, and detail work are all sewn and stitched, not printed.

check_box

How does the sizing run?

It’s designed as a baggy unisex kigurumi fit — roomy in the shoulders, sleeves, and legs by design. Order your normal size for the intended oversized look. If you’re between sizes or want it even baggier, size up. All four characters run the same.

check_box

How does the glow-in-the-dark version work?

The dorsal spikes and tail spikes are made from glow-in-the-dark fabric. Charge them under any light for a few minutes and they glow bright neon pink-magenta for 20+ minutes in the dark, staying faintly visible much longer. It recharges every time it sees light — no batteries, nothing to replace.

check_box

How long does shipping take?

Every order is a pre-order. Each kaiju is made to order — allow 6–8 weeks for production and delivery. Shipping is free worldwide and you’ll get tracking as soon as your order ships.

check_box

How do I wash it?

Machine wash cold on a gentle cycle, tumble dry low or hang to dry. The sherpa holds up well — customers report no pilling or fading after months of regular washing. Avoid high heat to protect the sculpted hood detail and the glow fabric.

check_box

Does it come with the tail and footies?

Yes. Everything you see is included — the sculpted hood, the stuffed tail with matching spikes, the built-in footies, and on the Kong onesie the oversized gorilla fist mittens. Nothing is a separate add-on.

check_box

What is your return policy?

All sales are final. Because every onesie is made to order, we don’t offer returns or exchanges. If your order arrives defective, contact us within 48 hours of delivery with photos and we’ll send a free replacement.

check_box

Can I get all three?

Absolutely, and plenty of people do. Godzilla, Kong, and Mothra are all right here on this page — just add each one to your cart. They look genuinely incredible together and matching group sets are one of our most common orders.
