The 2D Dream: Koharu 155cm K-Cup Anime STPE Doll
Bring your favorite illustrations to life with Koharu, a stunning tribute to the "short stack" anime aesthetic. From the specialists at IRKEBIJIN, Koharu is designed specifically for fans of hyper-exaggerated 2D proportions. Standing at a petite 155cm (5'1"), she features a gravity-defying K-cup bust and a waist so narrow it looks like it was drawn by a master manga artist.
Crafted from advanced STPE (Silicone-TPE Hybrid), Koharu offers the best of both worlds: the incredible softness and "fleshy" feel of TPE combined with the durability and refined skin texture of silicone.
Key Highlights
Authentic Anime Artistry: Featuring a stylized head with large, expressive eyes and a youthful, porcelain-smooth complexion that perfectly captures the "waifu" look.
Extreme K-Cup Silhouette: Koharu boasts a massive 90cm full bust contrasted against an impossibly small 48cm (18.9") waist, creating a visually striking silhouette that pushes the boundaries of realism.
Premium STPE Hybrid Material: Her skin is engineered to be less oily than traditional TPE while maintaining a soft, pillowy elasticity that makes her incredibly huggable.
Compact & Maneuverable: At just 35kg (77 lbs), Koharu is the ideal size for easy handling, dressing, and posing without sacrificing the presence of a full-body companion.
Articulated Versatility: Her internal steel skeleton allows for a wide range of motion, letting you recreate classic anime poses with precision and stability.

Koharu's 48cm waist is one of the smallest we've seen! Are you looking to complete the look with a specific cosplay outfit, or are you more interested in how that STPE material feels compared to standard TPE?
Koharu: Life-Size STPE 155cm K-Cup Anime Sex Doll-IRKEBIJIN
This full-size silicone doll is a specialty order item and is not stocked for immediate shipping.
Before production begins, we confirm the final configuration with our supplier. The default version means the doll is ordered exactly as shown in the product photos. Some models may also offer paid custom upgrades, including options such as implanted hair or a moaning / voice box.
Once the final configuration is confirmed, production usually takes 7 to 14 days. After production is complete, the supplier sends confirmation photos, which are provided to the customer for approval before shipping.
Shipping options may include ocean freight or air freight. Ocean freight is usually the lower-cost option and may take approximately 25 days after production. Air freight is faster and may take approximately 7 to 10 days after production, but additional freight charges apply.
Once production has started, a refund is not possible.
Because this is a specialty item, final pricing, customization options, and shipping costs should be confirmed before the order is finalized.
