Quick answer

Choose the 9 oz Boy Butter Water Based Cream Lubricant for portability and try-it-out value; pick the 16 oz Boy Butter H2O Formula for the best cost per ounce and extended home use.

Why size matters for water-based lube

Water-based lubricants like Boy Butter H2O are versatile and skin-friendly, but they do get used up faster than silicone or oil options. That makes choosing the right size a practical decision: too small and you reorder often; too large and you may not finish it before you want to try something new. Both sizes here share the same creamy, long-lasting formula, so your choice really comes down to volume and value.

Price per ounce trade-off

The 9 oz bottle (catalog price USD 19.14, compared to USD 29.00) works out to roughly USD 2.13 per ounce. The 16 oz bottle (catalog price USD 24.48, compared to USD 34.00) drops that to about USD 1.53 per ounce. That is a saving of around 28% per ounce when you go bigger. If you use lube weekly or more, the 16 oz size pays for itself in a few refills.

Portability and storage

The 9 oz squeeze bottle is compact enough for a nightstand drawer, gym bag, or travel kit. The 16 oz bottle is better left at home on a shelf. Neither is spill-proof, but the squeeze design of both makes one-handed application easy. If you move between locations, the smaller size wins.

Which size fits you? Decision rules

  • Buy the 9 oz if…: You travel often, want to test the formula before committing to a larger bottle, or store lube in multiple locations (e.g., bedroom and gym bag). The smaller bottle is also a good gift or starter size. 9 oz = portable, lower upfront cost, easy to replace.
  • Buy the 16 oz if…: You use water-based lube regularly (weekly or more), have a dedicated home storage spot, and want the best per-ounce value. The 16 oz saves you roughly 28% per ounce compared to the 9 oz. 16 oz = best value, fewer reorders, ideal for home.
  • Not sure? Start with 9 oz.: If you are new to Boy Butter H2O or water-based cream lubes in general, the 9 oz gives you enough volume to judge performance without overcommitting. You can always size up on your next order.
