About Whole Melt Extracts — The Standard for Premium Concentrate Vaping

Whole Melt Extracts traces its roots to the early days of cannabis concentrate innovation. Known for producing potent cannabis concentrates — whole melt wax, shatter, and terpene-rich oil — the brand has become widely recognised across the vaping community for consistent quality, powerful draws, and authentic strain-specific flavour.

The Phase series represents the brand’s ongoing hardware and extract evolution — from Phase 1 through to the current Phase 4 — each iteration refining the dual chamber system, improving airflow, enhancing vapour production, and deepening the flavour profile of the extracts inside. Phase 4 is the most advanced yet.

Dual Chamber System — Switch Between Strains Mid-Session

The Phase 4’s defining feature is its dual chamber system with independent flavour profiles — two unique strain-specific chambers in one device, allowing users to switch between strains mid-session. That means a smoother, more customisable experience whether you prefer fruity, gassy, or dessert-forward flavour notes.

Activating the Wholemelt switch system allows you to alternate between chambers effortlessly — eliminating the need to carry multiple pens or carts to access two different strain profiles. Two distinct extracts. One sleek device. Genuine dual-strain flexibility for both new and experienced THC vape users.

Premium Extract Quality — Phase 4 Craftsmanship

Each Phase 4 device is filled with premium Whole Melt Extracts concentrate — the same quality standard that made Whole Melt famous across the concentrate community. Terpene-rich, potent, and smooth — the Phase 4 delivers flavour depth and vapour performance that reflect the brand’s extract heritage.

Popular flavour profiles in the Phase 4 range include fruit-forward combinations, gassy/OG profiles, and dessert-inspired strain pairings — from Gelato and Banana Taffy to Guava Cocktail and Pineapple Diesel, the dual chamber format lets you pair two complementary or contrasting profiles in one device.

Superior Airflow and Vapour Production

Engineered with the latest Phase 4 hardware — powerful draws, superior airflow, and enhanced vapour production. The dual chamber system integrates independent airflow pathways per chamber, ensuring smooth transitions between strains without compromising vapour quality or flavour clarity. Each chamber delivers its own distinct extract character cleanly and consistently.

Authenticity Verified — QR Code Per Device
