The 230ml amber Boston bottle is the size where DIY blending becomes genuinely economical: enough capacity to refill just once a month, yet still comfortable to handle in daily bathroom use. The cap-free variant gives you the freedom to fit exactly the closure that suits your intended purpose.
The advantages of the larger size
At 230ml, you are approaching the standard size of commercial body lotions — meaning homemade body creams, shampoos and conditioners can be used at a normal daily pace without weekly refilling. In UV-protected amber glass, the contents stay fresher for longer — a fact that pays off even more at 230ml.
Multiple closure options
The DIN 18 threaded neck is compatible with lotion pumps, spray heads, screw caps and dropper heads. A pump head for body lotion or shampoo, a spray head for mists, a screw cap for concentrated extracts — you decide.
