20/400 Short-Pipette Brushed Matte Gold Dropper (35–42 mm) for Heavy-Base 30ml Facial Oil Bottles & 3×100ml Tube Window Gift Box Dieline Engineering

Exact 2026 B2B packaging engineering spec: custom-cut 38mm borosilicate pipettes (3mm bottom clearance) with satin matte gold 20/400 collars & oil-resistant NBR bulbs, plus 235×178×48mm 3-tube RPET window gift box & 115×225+35mm stand-up pouch dieline formulas. MOQ 500–3,400 pcs.

Module 1 · Heavy-Base 20/400 Short Glass Pipette Clearance Engineering

Solving bottom-out failure on squat heavy-punt 30 ml oil bottles.

Luxury facial oil brands increasingly specify squat, heavy-base 30 ml frosted glass cylinders (e.g., 53.0 mm total height × 49.0 mm outer diameter, GPI 20/400 neck finish with 11.5–13.0 mm solid glass base punt). Standard 1 oz catalog droppers ship with 75–78 mm glass pipettes designed for tall Boston rounds—causing immediate glass tip collision before the collar threads engage. Vella cuts Type-I borosilicate pipettes to exact custom exposed length L_exposed = H_bottle - t_punt - H_collar_datum - 3.0 mm (35.0–42.0 mm range, typically 38.0 mm ± 0.5 mm), pairing a genuinely non-shiny satin/brushed anodized matte gold aluminum collar (60–65 GU gloss cap eliminated down to 12–18 GU satin sheen) with an oil-resistant black high-ACN nitrile (NBR) or platinum-cured silicone bulb that resists squalane, rosehip, and citrus terpene swelling at 48°C for 30 days.

Module 2 · 3 × 100 mL Cosmetic Tube Window Gift Box & Cylindrical Pouch Dieline Matrix

Exact production dielines, tolerances & 2026 FOB pricing tiers.

When bundling three Ø40 mm × 145 mm (163 mm capped) 5-layer EVOH soft-touch matte tubes (Shampoo, Conditioner, Body Wash) into a retail presentation box with a left solid brand panel and right clear display window, Vella locks outer box geometry at 235 mm (W) × 178 mm (H) × 48 mm (D) in 350 gsm FSC C1S ivory board, allocating an 82 mm solid left panel, a 135 × 138 mm 0.25 mm anti-scratch RPET window, and a 350 gsm dyed-through matte-black 3-cavity cradle insert (three 41.0 mm recessed slots with 12 mm bridges). Similarly, for packing a single rigid cylindrical deodorant stick (Ø41.5 mm × H 162 mm) inside a resealable stand-up pouch, flat width follows W_flat = (π × D / 2) + 2 × Seal + Clearance = 115 mm (W) × 225 mm (H) + 35 mm bottom gusset in 0.12 mm Matte OPP / Cotton Paper / LLDPE with Pantone soft-touch matte + spot-gloss UV registration.
