Each birthday t-shirt is made from high-quality 100% cotton, selected for its softness, breathability and durability. The cotton is ethically sourced, making it gentle on young skin and suitable for all-day wear and play.
The space design features a cotton astronaut fabric patch, giving a tactile, raised texture that children love. The birthday number is carefully applied using professional-grade heat transfer vinyl, hand-pressed in my UK studio to ensure a secure and long-lasting finish.
These t-shirts are designed to be both fun and practical, standing up well to regular wear while remaining comfortable and soft.
